However, in 2004, a Neolithic grave was excavated in Shillourokambos, Cyprus, that contained the skeletons, laid close to one another, of both a human and a cat.<br /><br />The grave is estimated to be 9,500 years old, pushing back the earliest known feline-human association significantly. The cat specimen is large and closely resembles the African wildcat (Felis silvestris lybica), rather than present-day domestic cats. This discovery, combined with genetic studies, suggest that cats were probably domesticated in Cyprus and the Near East, in the Fertile Crescent around the time of the development of agriculture.<br /><br />In ancient Egypt cats were sacred animals, with the Bast often depicted in cat form, sometimes taking on the warlike aspect of a lioness. The Romans are often credited with introducing the domestic cat from Egypt to Europe; in Roman Aquitaine, a first or second century epitaph of a young girl holding a cat is one of two earliest depictions of the Roman domesticated cat.<br /><br />However, it is possible that cats were already kept in Europe prior to the Roman Empire, as they may have already been present in Britain in the late Iron Age. Domestic cats were spread throughout much of the rest of the world during the Age of Discovery, as they were carried on sailing ships to control shipboard rodents and as good-luck charms.<br /><p></p>Several ancient religions believed that cats are exalted souls, companions or guides for humans, that they are all-knowing but are mute so they cannot influence decisions made by humans. In Japan, the Maneki Neko is a cat that is a symbol of good fortune.<br /><br />Although there are no sacred species in Islam, some writers have stated that Muhammad had a favorite cat, Muezza. He is reported to have loved cats so much that "he would do without his cloak rather than disturb one that was sleeping on it".<br /><br />Freyja—the goddess of love, beauty, and fertility in Norse mythology—is depicted as riding a chariot drawn by cats. Many cultures have negative superstitions about cats. An example would be the belief that a black cat "crossing your path" leads to bad luck, or that cats are witches' familiars used to augment a witch's powers and skills. This led to the widespread extermination of cats in Europe in medieval times.<br /><br />The Black Plague was spread by fleas carried by infected rats, and the killing of cats ostensibly caused an increase in the rat population. The killing of cats in Medieval Ypres is commemorated in the innocuous present-day Kattenstoet (cat parade).<br /><br />According to a myth in many cultures, cats have multiple lives. In many countries, they are believed to have nine lives, but in some Spanish-speaking regions they are said to have seven lives, while in Turkish and Arabic traditions the number of lives is six.<br /><br />The myth is attributed to the natural suppleness and swiftness cats exhibit to escape life-threatening situations. Also lending credence to this myth is that falling cats often land on their feet because of an inbuilt automatic twisting reaction and are able to twist their bodies around to land feet first, though they can still be injured or killed by a high fall.<p><sup id="cite_ref-230" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-230"><span></span></a></sup></p><p><sup id="cite_ref-Mason223_223-1" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-Mason223-223"><span></span></a></sup></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-16495642385547236622010-04-03T20:42:00.000-07:002010-04-03T20:48:18.516-07:00Feral Cats<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_Ber2QzIQMms/S7gL9jWairI/AAAAAAAABXE/GfOVFxNDRvI/s1600/feral+cat-petlifestyleonline.com"><img style="float: right; margin: 0pt 0pt 10px 10px; cursor: pointer; width: 396px; height: 400px;" src="http://3.bp.blogspot.com/_Ber2QzIQMms/S7gL9jWairI/AAAAAAAABXE/GfOVFxNDRvI/s400/feral+cat-petlifestyleonline.com" alt="" id="BLOGGER_PHOTO_ID_5456124100648536754" border="0" /></a><br /><p><a href="http://en.wikipedia.org/wiki/Feral_cat" title="Feral cat"></a></p><span style="font-weight: bold;">Feral cats</span> are <span style="font-weight: bold;">wild cats</span> that are unfamiliar with humans and roam freely in urban or rural areas. The numbers of feral cats are not known, but estimates of the US feral population range from 25 to 60 million.<br /><br /><br /><br />Feral cats may live alone, but most are found in large groups called <span style="font-weight: bold;">feral colonies</span>, which occupy a specific territory and are usually associated with a source of food. Famous feral cat colonies are found in Rome around the Colosseum and Forum Romanum, with cats at some of these sites being fed and vetted by volunteers.<br /><br />Public attitudes towards feral cats vary widely: ranging from seeing them as <span style="font-weight: bold;">free-ranging pets</span>, to regarding them as vermin. One common approach to reducing the feral cat population is termed trap-neuter-return, where the cats are trapped, neutered, immunized against rabies and the feline leukemia virus, and then released.<br /><br />Before releasing them back into their feral colonies, the attending veterinarian often nips the tip off one ear to mark the feral as neutered and inoculated, since these cats may be trapped again.<br /><br />Volunteers continue to feed and give care to these cats throughout their lives, and not only is their lifespan greatly increased, but behavior and nuisance problems, due to competition for food, are also greatly reduced.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-69671053411786951552010-03-19T09:14:00.000-07:002010-03-19T09:28:13.761-07:00Waste<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_Ber2QzIQMms/S6Ol-sqtWBI/AAAAAAAABWI/E-mZ43tXSX8/s1600-h/cat+on+toilet.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 291px; height: 323px;" src="http://1.bp.blogspot.com/_Ber2QzIQMms/S6Ol-sqtWBI/AAAAAAAABWI/E-mZ43tXSX8/s400/cat+on+toilet.jpg" alt="" id="BLOGGER_PHOTO_ID_5450382470609197074" border="0" /></a><br /><p></p>Cats bury their urine and feces. Indoor cats are usually provided with a litter box containing litter, typically bentonite, but sometimes other absorbent material such as shredded paper or wood chips, or sometimes sand or similar material.<br /><br />It should be cleaned daily and changed often, depending on the number of cats in a household and the type of litter; if it is not kept clean, a cat may be fastidious enough to find other locations in the house for urination or defecation.<br /><br /><br /><br />This may also happen for other reasons; for instance, if a cat becomes constipated and defecation is uncomfortable, it may associate the discomfort with the litter box and avoid it in favor of another location. Daily attention to the litter box also serves as a monitor of the cat's health.<br /><br />Bentonite or clumping litter is a variation which absorbs urine into clumps which can be sifted out along with feces, and thus stays cleaner longer with regular sifting, but has sometimes been reported to cause health problems in some cats.<br /><br />Those with toxoplasmosis-infected cats living in habitat areas of sea otters may wish to dispose of droppings in the trash, rather than flushing them down the toilet. Some cats can be trained to use the human toilet, eliminating the litter box and its attendant expense, unpleasant odor, and the need to use landfill space for disposal.<br /><br />Training may involve four to six weeks of incremental moves, such as moving and elevating the litter box until it is near the toilet, as well as employing an adapter such as a bowl or small box to suspend the litter above the toilet bowl. When training is complete, the cat uses the toilet by squatting on the toilet seat over the bowl.<p></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-58010966841226056952010-03-12T08:08:00.000-08:002010-03-12T08:24:38.526-08:00Indoor Scratching<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_Ber2QzIQMms/S5pqtZvjqPI/AAAAAAAABV4/WNbFjPhCbwk/s1600-h/cat+scratching.jpg"><img style="float: right; margin: 0pt 0pt 10px 10px; cursor: pointer; width: 305px; height: 400px;" src="http://1.bp.blogspot.com/_Ber2QzIQMms/S5pqtZvjqPI/AAAAAAAABV4/WNbFjPhCbwk/s400/cat+scratching.jpg" alt="" id="BLOGGER_PHOTO_ID_5447784027495049458" border="0" /></a><br />A natural behavior in cats is to periodically hook their front claws into suitable surfaces and pull backwards. This marks territory, exercises their legs, as well as cleaning and sharpening their claws.<br /><br />Indoor cats benefit from being provided with a scratching post so that they are less likely to use carpet or furniture which they can easily ruin.<br /><br />Commercial scratching posts typically are covered in carpeting or upholstery, but some authorities advise against this practice, as not making it clear to the cat which surfaces are permissible and which are not; they suggest using a plain wooden surface, or reversing the carpeting on the posts so that the rougher texture of the carpet backing is a more attractive alternative to the cat than the floor covering.<br /><br />Scratching posts made of sisal rope or corrugated cardboard are also common.<br /><br />Although scratching can serve cats to keep their claws from growing excessively long, their nails can be trimmed if necessary. Another response to indoor scratching is onychectomy, commonly known as declawing.<br /><br />This is a surgical procedure to remove the claw and first bone of each digit of a <span style="font-weight: bold;">cat's paws</span>. Declawing is most commonly only performed on the front feet. A related procedure is tendonectomy, which involves cutting a tendon needed for cats to extend their claws.<br /><br /><span style="font-weight: bold;">Declawing</span> is a major surgical procedure and can produce pain, infections and permanent lameness. Since this surgery is not performed for the benefit of the animal, it is controversial and remains uncommon outside of North America.<br /><br />In many countries, it is prohibited by animal welfare laws. Although widely practiced in the US, declawing is ethically controversial within the American veterinary community. Both the Humane Society and the American Society for the Prevention of Cruelty to Animals strongly discourage or condemn the procedure.Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-5740819718656212358.post-27040577571777926552010-03-03T19:15:00.000-08:002010-03-03T19:51:07.639-08:00Effects On Human Health<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_Ber2QzIQMms/S48uH_V6xVI/AAAAAAAABVg/TClnRrDMIO4/s1600-h/sleeping+cat.jpg"><img style="float: left; margin: 0pt 10px 10px 0pt; cursor: pointer; width: 400px; height: 240px;" src="http://3.bp.blogspot.com/_Ber2QzIQMms/S48uH_V6xVI/AAAAAAAABVg/TClnRrDMIO4/s400/sleeping+cat.jpg" alt="" id="BLOGGER_PHOTO_ID_5444621189311546706" border="0" /></a><br /><p></p>Because of their small size, domesticated <span style="font-weight: bold;">house cats</span> pose little physical danger to adult humans. However, in the USA cats inflict about 400,000 bites per year, with 90% of these bites coming from provoked animals; this number represents about one in ten of all animal bites.<br /><br /><br /><br />Many cat bites will become infected, sometimes with serious consequences such as <span style="font-weight: bold;">cat-scratch disease</span>, or, more rarely, rabies. Cats may also pose a danger to pregnant women and immune suppressed individuals, since their feces can transmit toxoplasmosis.<br /><br />A large percentage of cats are infected with this parasite, with infection rates ranging from around 40 to 60% in both domestic and stray cats worldwide. Allergic reactions to cat dander and/or cat saliva are common.<br /><br />Some humans who are allergic to cats—typically manifested by hay fever, asthma, or a skin rash—quickly acclimate themselves to a particular animal and live comfortably in the same house with it, while retaining an allergy to cats in general.<br /><br />Whether the risk of developing allergic diseases such as asthma is increased or decreased by cat ownership is uncertain. Some owners cope with this problem by taking allergy medicine, along with bathing their cats frequently, since weekly bathing will reduce the amount of dander shed by a cat.<br /><br />There have also been attempts to <span style="font-weight: bold;">breed hypoallergenic cats</span>, which would be less likely to provoke an allergic reaction. As well as posing health risks, interactions with cats may improve health and reduce physical responses to stress: for example the presence of cats may moderate increased blood pressure.<br /><br />Cat ownership may also improve psychological health by providing emotional support and dispelling feelings of depression, anxiety and loneliness. Indeed, their ability to provide companionship and friendship are common reasons given for owning a cat.<p><sup id="cite_ref-Gallup_181-1" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-Gallup-181"><span></span></a></sup></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-33238503554106442122010-02-25T07:38:00.000-08:002010-02-25T07:49:14.717-08:00Cat Coat pattern<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_Ber2QzIQMms/S4ab6-rZWTI/AAAAAAAABVY/dXWKafST3UA/s1600-h/bobcat.jpg"><img style="float: right; margin: 0pt 0pt 10px 10px; cursor: pointer; width: 400px; height: 314px;" src="http://1.bp.blogspot.com/_Ber2QzIQMms/S4ab6-rZWTI/AAAAAAAABVY/dXWKafST3UA/s400/bobcat.jpg" alt="" id="BLOGGER_PHOTO_ID_5442208637283555634" border="0" /></a><br /><dl><dt><span style="font-weight: bold;">Colorpoint</span><br /></dt></dl>The <span style="font-weight: bold;">colorpoint pattern</span> is most commonly associated with <span style="font-weight: bold;">Siamese cats</span>, but may also appear in any <span style="font-weight: bold;">domesticated cat</span>. A colorpointed cat has dark colors on the face, ears, feet, and tail, with a lighter version of the same color on the rest of the body, and possibly some white.<br /><br /><br /><br />The exact name of the colorpoint pattern depends on the actual color, so there are seal points (dark brown), chocolate points (warm lighter brown), blue points (dark gray), lilac or frost points (silvery gray-pink), red or flame points (orange), and tortie (tortoiseshell mottling) points, among others.<br /><br />This pattern is the result of a temperature sensitive mutation in one of the enzymes in the metabolic pathway from tyrosine to pigment, such as melanin; thus, little or no pigment is produced except in the extremities or points where the skin is slightly cooler.<br /><br />For this reason, colorpointed cats tend to darken with age as bodily temperature drops; also, the fur over a significant injury may sometimes darken or lighten as a result of temperature change. The tyrosine pathway also produces neurotransmitters, thus mutations in the early parts of that pathway may affect not only pigment, but also neurological development.<br /><br />This results in a higher frequency of cross-eyes among colorpointed cats, as well as the high frequency of cross-eyes in white tigers.<br /><br /><span style="font-weight: bold;">White cats</span><br /><br />True albinism (a mutation of the tyrosinase gene) is quite rare in cats. Much more common is the appearance of white coat color due to a lack of melanocytes in the skin. A higher frequency of deafness in white cats is due to a reduction in the population and survival of melanoblast stem cells, which in addition to creating pigment producing cells, develop into a variety of neurological cell types. White cats with one or two blue eyes have a particularly high likelihood of being deaf.<br /><dl><dt><br /></dt><span style="font-weight: bold;">Smoke cats</span><br /><br />The bottom eighth of each hair is white or creamy-white, with the rest of the hair being a solid color. Genetically this color is a non-agouti cat with the dominant inhibitor gene; a non-agouti version of the silver tabby.

Bicolor cats can have as their primary (non-white) color black, red, any dilution thereof, and tortoiseshell (see below for definition).<br /><br /><dt><a href="http://en.wikipedia.org/wiki/Tabby_cat" title="Tabby cat"></a><br /></dt>Tabby cat<br /><br />Striped, with a variety of patterns. The classic blotched tabby (or marbled) pattern is the most common and consists of butterflies and bullseyes. The mackerel or striped tabby is a series of vertical stripes down the cat's side (resembling the fish).<br /><br />This pattern broken into spots is referred to as a spotted tabby. Finally, the tabby markings may look like a series of ticks on the fur, thus the ticked tabby, which is almost exclusively associated with the Abyssinian breed of cats.<br /><br />The worldwide evolution of the cat means that certain types of tabby are associated with certain countries; for instance, blotched tabbies are quite rare outside NW Europe, where they are the most common type.<br /><br /><dt><a href="http://en.wikipedia.org/wiki/Tortoiseshell_cat" title="Tortoiseshell cat"></a><br /></dt>Tortoiseshell and Calico<br /><br />This cat is also known as a Calimanco cat or Clouded Tiger cat, and by the nickname "tortie." In the cat fancy, a tortoiseshell cat is randomly patched over with red (or its dilute form, cream) and black (or its dilute blue) mottled throughout the coat.<br /><br />Additionally, the cat may have white spots in its fur, which make it a "tortoiseshell and white" cat or, if there is a significant amount of white in the fur and the red and black colors form a patchwork rather than a mottled aspect, the cat will be called a calico. All calicos are tortoiseshell (as they carry both black and red), but not all tortoiseshells are calicos (which requires a significant amount of white in the fur and patching rather than mottling of the colors).<br /><br />The calico is also sometimes called a tricolor cat. The Japanese refer to this pattern as mi-ke (meaning "triple fur"), while the Dutch call these cats lapjeskat (meaning "patches cat"). A true tricolor must consist of three colors: a reddish color, dark or light; white; and one other color, typically a brown, black, or blue.<br /><br />Both tortoiseshell and calico cats are typically female because the coat pattern is the result of differential X chromosome inactivation in females (which, as with all normal female mammals, have two X chromosomes). Conversely, cats where the overall color is ginger (orange) are commonly male (roughly in a 3:1 ratio). In a litter sired by a ginger tom, the females will be tortoiseshell or ginger.<br /><br />Male tortoiseshells can occur as a result of chromosomal abnormalities (often linked to sterility) or by a phenomenon known as mosaicism, where two early stage embryos are merged into a single kitten.<br /><dd><br /></dd></dl>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-20908443667301900642010-02-11T13:35:00.000-08:002010-02-11T13:36:51.120-08:00Cat Varieties<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_Ber2QzIQMms/S3R4YX67IXI/AAAAAAAABU4/Cwwc9PnyGAE/s1600-h/different-cat-breeds.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 400px; height: 297px;" src="http://3.bp.blogspot.com/_Ber2QzIQMms/S3R4YX67IXI/AAAAAAAABU4/Cwwc9PnyGAE/s400/different-cat-breeds.jpg" alt="" id="BLOGGER_PHOTO_ID_5437103010276385138" border="0" /></a><br />Cats are a common companion animal in Europe and North America, and their worldwide population exceeds 500 million. In 1998 there were around 43 million cats in Western Europe, 33 million in Eastern Europe, seven million in Japan and three million in Australia.<br /><br />A 2007 report stated that about 37 million US households owned cats, with an average of 2.2 cats per household giving a total population of around 82 million. This is slightly more than the 72 million pet dogs in that country.<br /><br />Although cat ownership has commonly been associated with women,a 2007 Gallup poll reported that men and women were equally likely to own a cat.The ratio of pedigree/purebred cats to random-bred cats varies from country to country. However, generally speaking, purebreds are less than ten percent of the total population.<br /><br />According to the Humane Society of the United States, as well as being kept as pets, cats are also used in the international fur trade. About 24 cats are needed to make a cat fur coat, although cat fur is also used in gloves, hats, shoes, blankets and stuffed toys.This use has now been outlawed in several countries, including the United States, Australia and the European Union.<br /><br />However, some cat furs are still made into blankets in Switzerland as folk remedies that are believed to help rheumatism. It has long been common for cats to be eaten in some parts of China and in some other Asian countries. According to the Chengdu Business Daily, people in southern China's Guangdong province ate 10,000 cats a day. Animal People estimates that 4 million cats are killed and consumed in Asia every year.<br /><br />The concept of a cat breed appeared in Britain during the late 19th century. The current list of cat breeds is quite large: with the Cat Fanciers' Association recognizing 41 breeds, of which 16 are "natural breeds" that probably emerged before humans began breeding pedigree cats, while the others were developed over the latter half of the 20th century.<br /><br />The owners and breeders of show cats compete to see whose animal bears the closest resemblance to the "ideal" definition and standard of the breed. Because of common crossbreeding in populated areas, many cats are simply identified as belonging to the homogeneous breeds of domestic longhair and domestic shorthair, depending on their type of fur.<br /><br />In the United Kingdom and Australasia, non-purebred cats are referred in slang as moggies (derived from "Maggie", short for Margaret, reputed to have been a common name for cows and calves in 18th century England and latter applied to housecats during the Victorian era).<br /><br />In the United States, a non-purebred cat is sometimes referred to in slang as a barn or alley cat, even if it is not a stray. Cats come in a variety of colors and patterns. These are physical properties and should not be confused with a breed of cat. Some original cat breeds that have a distinct phenotype that is the main type occurring naturally as the dominant domesticated cat type in their region of origin are sometimes considered as subspecies and also have received names as such in nomenclature, although this is not supported by feline biologists. Some of these cat breeds are:<br /><ul><li><i>F. catus anura</i> - the Manx</li><li><i>F. catus siamensis</i> - the Siamese</li><li><i>F. catus cartusenensis</i> - the Chartreux</li><li><i>F. catus angorensis</i> - the Turkish Angora</li></ul><br /><div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

Current UK assessments indicate that they may be accountable for an estimated 64.8 million bird deaths each year.<br /><br />Certain species appear more susceptible than others; for example, 30% of <span style="font-weight: bold;">house sparrow</span> mortality is linkmd to the domestic cat. In the recovery of ringed robins and dunnocks, it was also concluded that 31% of deaths were a result of cat predation.<br /><br />On islands, birds can contribute as much as 60% of a cat’s diet. In nearly all cases, however, the cat cannot be identified as the sole cause for reducing the numbers of island birds, and in some instances eradication of cats has caused a ‘mesopredator release’ effect; where the suppression of top<span style="font-weight: bold;"> carnivores creates</span> an abundance of smaller predators that cause a severe decline in their shared prey.<br /><br /><span style="font-weight: bold;">Domestic cats</span> are, however, known to be a contributing factor to the decline of many species; a factor that has ultimately led, in some cases, to extinction. The South Island Piopio; Chatham Islands Rail; the Auckland Islands Merganser; and the common diving petrel are a few from a long list, with the most extreme case being the flightless Stephen Island Wren, which was driven to extinction only a few years after its discovery.<br /><br />Some of the same factors that have promoted adaptive radiation of island avifauna over evolutionary time appear to promote vulnerability to non-native species in modern time. The susceptibility inherent of many island birds is undoubtedly due to evolution in the absence of mainland predators, competitors, diseases and parasites.<br /><br />In addition to lower reproductive rates and extended incubation periods. The loss of flight, or reduced flying ability is also characteristic of many island endemics. These biological aspects have increased vulnerability to extinction in the presence of introduced species, such as the domestic cat.<br /><br />Equally, behavioural traits exhibited by island species, such as ‘predatory naivety’ and ground-nesting, have also contributed to their susceptibility.<p></p> <div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

They are extremely adaptable and are now present on all the continents (including Antarctica) and on 118 of 131 main groups of islands.<br /><br /><span style="font-weight: bold;">Feral cats</span> can live in forests, grasslands, tundra, coastal areas, agricultural land, scrublands, urban areas and wetlands. Their habitats even include small oceanic islands with no human inhabitants. However, this ability to thrive in almost any terrestrial habitat has led the cat's designation as one of the world's worst invasive species.<br /><br /><br /><br />Despite this general adaptability, the close relatives of domestic cats, the <span style="font-weight: bold;">African Wildcat</span> (Felis silvestris lybica) and the <span style="font-weight: bold;">Arabian Sand Cat</span> (Felis margarita) both inhabit desert environments, and domestic cats still show similar adaptations and behaviors.<br /><br />To date, there are few scientific data available to assess the impact of cat predation on prey populations. Cat numbers are growing annually and their abundance is far above the ‘natural’ carrying capacity, due to their population sizes being independent of their prey’s dynamics – i.e. cats are ‘recreational’ hunters.<br /><br />Population densities can be as high as 2000 individuals per km2[155] and the current trend is an increase of 0.5 million cats annually. Even well-fed <span style="font-weight: bold;">domestic cats</span> may hunt and kill, mainly catching small mammals, but also birds, amphibians, reptiles, fish and invertebrates.<br /><br />Hunting by domestic cats may be contributing to the decline in the numbers of birds in urban areas, although the importance of this effect remains controversial. In the wild, the introduction of feral cats during human settlement can threaten native species with extinction.<br /><br />In many cases controlling or eliminating the populations of non-native cats can produce a rapid recovery in native animals. However, the ecological role of introduced cats can be more complicated: for example, cats can control the numbers of rats, which also prey on birds' eggs and young, so in some cases eliminating a cat population can actually accelerate the decline of an endangered bird species in the presence of a mesopredator, controlled by cats.<br /><br />In the Southern Hemisphere, cats are a particular problem in landmasses such as Australasia, where cat species have never been native and there were few equivalent native medium-sized mammalian predators.<br /><br />Native species such as the New Zealand Kakapo and the Australian Bettong, for example, tend to be more ecologically vulnerable and behaviorally "naive" to predation by feral cats. Feral cats have had a major impact on these native species and have played a leading role in the endangerment and extinction of many animals.<p><sup id="cite_ref-MacDonald_25-9" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-MacDonald-25"><span></span></a></sup></p> <h3><span class="mw-headline" id="Impact_on_prey_species"><br /></span></h3><div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

Heat periods occur about every two weeks and last about 4 to 7 days.<br /><br />Multiple males will be attracted to a female in heat. The males will fight over her, and the victor wins the right to mate. At first, the female will reject the male, but eventually the female will allow the male to mate. The female will utter a loud yowl as the male pulls out of her.<br /><br />This is because a <span style="font-weight: bold;">male cat</span>'s penis has a band of about 120-150 backwards-pointing spines, which are about one millimeter long; upon withdrawal of the penis, the spines rake the walls of the female's vagina, which is a trigger for ovulation. After mating, the female will wash her vulva thoroughly.<br /><br />If a male attempts to breed with her at this point, the female will attack him. After about 20 to 30 minutes, once the female is finished grooming, the cycle will repeat. Because ovulation is not always triggered by a single mating, females may not be impregnated by the first male with which they mate.<br /><br />Furthermore,<span style="font-weight: bold;"> cats are superfecund</span>; that is, a female may mate with more than one male when she is in heat, with the result that different kittens in a litter may have different fathers. The gestation period for cats is between 64–67 days, with an average length of 66 days.<br /><br />The size of a litter averages three to five kittens, with the first litter usually smaller than subsequent litters. Kittens are weaned at between six and seven weeks, and cats normally reach sexual maturity at 5–10 months (females) and to 5–7 months (males), although this can vary depending on breed.<br /><br />Females can have two to three litters per year, so may produce up to 150 kittens in their breeding span of around ten years. Cats are ready to go to new homes at about 12 weeks old, or when they are ready to leave their mother. Cats can be surgically sterilized (spayed or castrated) as early as 7 weeks to limit unwanted reproduction.<br /><br />This surgery also prevents undesirable sex-related behavior, such as aggression, territory marking (spraying urine) in males and yowling (calling) in females. Traditionally, this surgery was performed at around six to nine months of age, but it is increasingly being performed prior to puberty, at about three to six months. In the USA approximately 80% of household cats are neutered.<p><sup id="cite_ref-145" class="reference"><a href="http://en.wikipedia.org/wiki/Cats#cite_note-145"><span></span></a></sup></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-53176966635645752112009-12-18T09:02:00.000-08:002009-12-18T09:18:17.677-08:00Cat Hunting<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_Ber2QzIQMms/Syu5QQ8KUVI/AAAAAAAABQw/tHKtRbLY7go/s1600-h/cat_hunting.png"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 271px; height: 283px;" src="http://1.bp.blogspot.com/_Ber2QzIQMms/Syu5QQ8KUVI/AAAAAAAABQw/tHKtRbLY7go/s400/cat_hunting.png" alt="" id="BLOGGER_PHOTO_ID_5416626665919500626" border="0" /></a><br /><p></p>Cats feed on small prey, primarily birds and rodents. <span style="font-weight: bold;">Feral cats</span> and<span style="font-style: italic;"> house cats</span> that are free-fed tend to consume many small meals in a single day, although the frequency and size of meals varies between individuals.<br /><br />Cats use two hunting strategies, either stalking prey actively, or waiting in ambush until an animal comes close enough to be captured. Although it is not certain, the type of strategy used may depend on the prey species in the area, with for example, cats waiting in ambush outside burrows, but tending to actively stalk birds.<br /><br />Most breeds of cat have a noted fondness for settling in high places, or perching. In the wild, a higher place may serve as a concealed site from which to hunt; domestic cats may strike prey by pouncing from such a perch as a tree branch, as does a leopard.<br /><br />Other possible explanations include that height gives the cat a better observation point, allowing it to survey its territory. During a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and flexibility. This is known as the cat's "righting reflex".<br /><br />It always rights itself in the same way, provided it has the time to do so, during a fall. The height required for this to occur is around 90 cm (3 feet). Cats without a tail also have this ability, since a cat mostly moves its hind legs and relies on conservation of angular momentum to set up for landing, and the tail is in fact little used for this feat.<br /><p></p>One poorly understood element of <span style="font-weight: bold;">cat hunting</span> behavior is the presentation of prey to human owners. Ethologist Paul Leyhausen proposed that cats adopt humans into their social group, and share excess kill with others in the group according to the local pecking order, in which humans are placed at or near the top.<br /><br />However, anthropologist and animal scientist Desmond Morris, in his 1986 book Catwatching, suggests that when cats bring home mice or birds, they are teaching their human to hunt, or helping their human as if feeding "an elderly cat, or an inept kitten". However, this proposal is inconsistent with the fact that male cats also bring home prey, despite males having no involvement with raising kittens.<br /><br />Domestic cats select food based on its temperature, smell and texture, strongly disliking chilled foods and responding most strongly to moist foods rich in amino acids, which are similar to meat.Cats may reject novel flavors (a response termed neophobia) and learn quickly to avoid foods that have tasted unpleasant in the past.<br /><br />They may also avoid sugary foods and milk; since they are lactose intolerant, these sugars are not easily digested and may cause soft stools or diarrhea. They can also develop odd eating habits. Some cats like to eat or chew on other things, most commonly wool, but also plastic, paper, string, or even coal. This condition is called pica and can threaten their health, depending on the amount and toxicity of the items eaten.<p><sup id="cite_ref-130" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-130"><span></span></a></sup></p><a href="http://en.wikipedia.org/wiki/Cat#cite_note-125"></a><div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

These are quite rigid as they contain keratin. These spines allow cats to groom themselves by licking their fur, with the rows of papillae acting like a hairbrush.<br /><br />Some cats, particularly longhaired cats, occasionally regurgitate hairballs of fur that have collected in their stomachs from grooming. These clumps of fur are usually sausage-shaped and about two to three centimeters long. Hairballs can be prevented with remedies that ease elimination of the hair through the gut, as well as regular grooming of the coat with a comb or stiff brush.<br /><br />In domestic cats, males are more likely to fight than females. In feral cats, the most common reason for cat fighting is when two males are competing to mate with a female: here most fights will be won by the heavier male.<br /><br />Another possible reason for fighting in domestic cats is when the cats have difficulties in establishing a territory within a small home. Female cats will also fight over territory or to defend their kittens. Spaying females and neutering males will decrease or eliminate this behavior in many cases.<br /><br /><span style="font-weight: bold;">Fighting cats</span> make themselves appear more impressive and threatening by raising their fur and arching their backs, thus increasing their apparent size. Attacks usually comprise powerful slaps to the face and body with the forepaws as well as bites, but serious damage is rare; usually the loser runs away with little more than a few scratches to the face, and perhaps the ears.<br /><br />Cats will also throw themselves to the ground in a defensive posture to rake their opponent's belly with their powerful hind legs. Normally, serious injuries from fighting will be limited to infections of scratches and bites, though these can occasionally kill cats if untreated.<br /><br />In addition, bites are probably the main route of transmission of feline immunodeficiency virus (FIV). Sexually active males will usually be in many fights during their lives, and often have decidedly battered faces with obvious scars and cuts to the ears and nose.<br /><br /><br /><sup id="cite_ref-hairballs_114-1" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-hairballs-114"><span></span></a></sup><div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

The timing of cats' activity is quite flexible and varied, which means that<span style="font-weight: bold;"> house cats</span> may be more active in the morning and evening (crepuscular behavior), as a response to greater human activity at these times.<br /><br /><br />House cats have territories that vary quite a lot in size, in one study ranging from seven to 28 hectares. Although they spend the majority of their time in the vicinity of their home, they can range many hundreds of meters from this central point. Cats conserve energy by sleeping more than most animals, especially as they grow older.<br /><br />The daily duration of sleep varies, usually 12–16 hours, with 13–14 being the average. Some cats can sleep as much as 20 hours in a 24-hour period. The term cat nap refers to the cat's ability to fall asleep (lightly) for a brief period and has entered the English lexicon—someone who nods off for a few minutes is said to be "taking a<span style="font-weight: bold;"> cat nap</span>".<br /><br />Cats are a social species, and free-living cats tend to form feral cat colonies if there is sufficient food, which are based around groups of co-operating females. Within this group one cat is usually dominant over the others. Each cat in a colony holds a distinct territory, with sexually active males having the largest territories, which are about ten times larger than those of female cats and may overlap with several females' territories.<br /><br />These territories are marked by urine spraying, by rubbing objects at head height with secretions from facial glands and by defecation. Between these territories are neutral areas where cats watch and greet one another without territorial conflicts.<br /><br />Outside these neutral areas, territory holders usually chase away stranger cats, at first by staring, hissing, and growling, and if that does not work, by short but noisy and violent attacks. Despite some cats cohabiting in colonies, cats do not have a social survival strategy, or a pack mentality and always hunt alone.<br /><br />As part of cat sociability they use a variety of vocalizations for communication, including meowing, purring, "trilling", hissing, growling, squeaking, chirping, clicking, and grunting. Their types of body language: position of ears and tail, relaxation of whole body, kneading of paws, are all indicators of mood.<br /><br />The tail and ears are particularly important social signal in cats, with a raised tail acting as a friendly greeting. Tail raising also indicates the cat's position in the group's social hierarchy, with dominant individuals raising their tails less often than subordinate animals.<br /><br />Nose-touching is also a common greeting and may be followed by social grooming, which is solicited by one of the cats raising and tilting its head. However, some pet cats are poorly socialized. In particular older cats may show aggressiveness towards newly-arrived kittens, which may include biting and scratching; this type of behavior is known as Feline Asocial Aggression.<br /><br />For cats, life in proximity with humans (and other animals kept by humans) amounts to a "symbiotic social adaptation". They may express great affection towards their human companions, especially if they imprint on them at a very young age and are treated with consistent affection.<br /><br />It has been suggested that, ethologically, the human keeper of a cat functions as a sort of surrogate for the cat's mother, and that adult domestic cats live their lives in a kind of extended kittenhood, a form of behavioral neoteny.<br /><p></p><div id="seolinx-tooltip" style="border: 1px solid rgb(0, 0, 0);

Some say that domesticated cats tend to live longer if they are not permitted to go outdoors (reducing the risk of injury from fights or accidents and exposure to diseases).<br /><br />However, this is not always necessarily true, because a cat kept indoors is more inclined to have a shortened life due to obesity (sometimes leading to heart problems and diabetes) and lack of exercise. Having a cat be neutered, however, is almost universally regarded as a health benefit.<br /><br />Some benefits of neutering are that castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. The lifespan of feral cats is hard to determine accurately, although one study reported a median age of 4.7 years, with a range between 0 to 10 years.<br /><br />Cats can suffer from a wide range of health problems, including infectious diseases, parasites, injuries and chronic disease. Vaccinations are available for many of these diseases, and domestic cats are regularly given treatments to eliminate parasites such as worms and fleas.<br /><br /><p></p>In addition to obvious dangers such as rodenticides, insecticides and weed killers, cats may be poisoned by many chemicals that are usually considered safe. This is because their livers are less effective at some forms of detoxification than those of other animals, including humans and dogs. Some of the most common causes of poisoning in cats are antifreeze and rodent baits.<br /><br />It has also been suggested that cats may be particularly sensitive to environmental pollutants. When a cat has a sudden or prolonged serious illness without any obvious cause, it is therefore possible that it has been exposed to a toxin. Human medicines should never be given to cats. For example, the painkiller paracetamol (also called acetaminophen), sold under brand names such as Tylenol and Panadol is extremely toxic to cats: even very small doses can be fatal and need immediate treatment.<br /><br />Even aspirin, which is sometimes used to treat arthritis in cats, is much more toxic to them than to humans and must be administered cautiously. Similarly, application of minoxidil (Rogaine) to the skin of cats, either accidentally or by well-meaning owners attempting to counter loss of fur, has sometimes been fatal.<br /><br />Essential oils can be toxic to cats and there have been reported cases of serious illnesses caused by tea tree oil, and tea tree oil-based flea treatments and shampoos. Other common household substances that should be used with caution around cats include mothballs and other naphthalene products.<br /><br />Phenol-based products are often used for cleaning and disinfecting near cats' feeding areas or litter boxes: such as Pine-Sol, Dettol (Lysol) or hexachlorophene, but these can sometimes be fatal. Ethylene glycol, often used as an automotive antifreeze, is particularly appealing to cats, and as little as a teaspoonful can be fatal.<br /><br />Some human foods are toxic to cats; for example theobromine in chocolate can cause theobromine poisoning, although few cats will eat chocolate. Large amounts of onions or garlic are also poisonous to cats. Many houseplants are also dangerous, such as Philodendron species and the leaves of the Easter Lily, which can cause permanent and life-threatening kidney damage.<br /><a href="http://en.wikipedia.org/wiki/Cat#cite_note-89"><span></span></a>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-12350506632397456952009-11-18T05:18:00.000-08:002009-11-18T05:24:59.797-08:00Cats Physiology<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_Ber2QzIQMms/SwP1nyJ9CTI/AAAAAAAABPA/H2-QTl5DZ4c/s1600/cats.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 400px; height: 283px;" src="http://2.bp.blogspot.com/_Ber2QzIQMms/SwP1nyJ9CTI/AAAAAAAABPA/H2-QTl5DZ4c/s400/cats.jpg" alt="" id="BLOGGER_PHOTO_ID_5405434041601952050" border="0" /></a><br /><p></p>As a familiar and <span style="font-weight: bold;">easily-kept animal</span>, the <span style="font-weight: bold;">physiology of cats</span> has been particularly well studied and is generally similar to that of other <span style="font-weight: bold;">carnivorous mammals</span>. However, several features of <span style="font-weight: bold;">cats' physiology</span> are unusual and are probably due to their descent from desert-dwelling species.<br /><br />For instance, cats are able to tolerate quite high temperatures, with humans starting to feel uncomfortable when their skin temperature passes about 44.5 °C (112 °F), in contrast cats show no discomfort until their skin reaches around 52 °C (126 °F). Unusually, a<span style="font-weight: bold;"> cat's body</span> temperature does not vary throughout the day; this is part of cats' general lack of circadian rhythms and may reflect their tendency to be active in both day and night.<br /><br />As well as being tolerant of high temperatures, cats' feces are usually dry and their urine is also highly concentrated, both of which are adaptations that allow cats to retain as much fluid as possible. Indeed, their kidneys are so efficient that cats can survive on a diet consisting only of meat, with no additional water, and can even rehydrate by drinking seawater.<br /><br />Cats are obligate carnivores: their physiology has evolved to efficiently process meat, and they have difficulty digesting plant matter. In contrast to omnivores such as rats, which only require about 4% protein in their diet, about 20% of a cat's diet must be protein.<br /><br />Cats are unusually dependent on a constant supply of the amino acid arginine, and a diet lacking arginine causes marked weight loss and can be rapidly fatal. Another unusual feature is that the cat also cannot produce the amino acid taurine, with taurine deficiency causing macular degeneration, where the cat's retina slowly degenerates, causing irreversible blindness.<br /><br />Since cats tend to eat all of their prey, they obtain minerals by digesting animal bones and a diet composed only of meat may cause calcium deficiency. A cat's digestive tract is also adapted to meat eating, being much shorter than that of omnivores and having low levels of several of the digestive enzymes that are needed to digest carbohydrates.<br /><br />These traits severely limits the cat's ability to digest and use plant-derived nutrients, as well as certain fatty acids. Despite the cat's meat-oriented physiology, several vegetarian or vegan cat foods have been marketed that are supplemented with chemically synthesized taurine and other nutrients, in attempts to produce a complete diet.<br /><br />However, some of these products still fail to provide all the nutrients that cats require, and diets containing no animal products pose the risk of causing severe nutritional deficiencies.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-90005697800339473732009-11-12T05:07:00.000-08:002009-11-12T05:14:34.191-08:00Cat Genetics<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_Ber2QzIQMms/SvwKKOChZlI/AAAAAAAABOg/OE6mtKRnHB4/s1600-h/Burmese+cats.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 400px; height: 252px;" src="http://4.bp.blogspot.com/_Ber2QzIQMms/SvwKKOChZlI/AAAAAAAABOg/OE6mtKRnHB4/s400/Burmese+cats.jpg" alt="" id="BLOGGER_PHOTO_ID_5403204823621396050" border="0" /></a><br /><p></p>The <span style="font-weight: bold;">domesticated cat</span> and its closest <span style="font-weight: bold;">wild ancestor</span> are both diploid organisms that possess 38 chromosomes and roughly 20,000 genes. About 250 heritable genetic disorders have been identified in cats, many similar to human inborn errors.<br /><br /> The high level of similarity among the metabolisms of mammals allows many of these feline diseases to be diagnosed using genetic tests that were originally developed for use in humans, as well as the use of cats in the study of the human diseases.<br /><br />An interesting example of a mutation that is shared among all felines, including the big cats, is a mutant chemosensor in their taste buds that prevents them from tasting sweetness, which may explain their indifference to fruits, berries, and other sugary foods. In some breeds of cats congenital deafness is very common, with most white cats (but not albinos) being affected, particularly if they also have blue eyes.<br /><br />The genes responsible for this defect are unknown, but the disease is studied in the hope that it may shed light on the causes of hereditary deafness in humans. Since a large variety of different coat patterns exist within the various cat breeds, the cat is an excellent animal to study the coat genetics of hair growth and coloration.<br /><br />Several genes interact to produce cats' hair color and coat patterns. Different combinations of these genes give different phenotypes. For example, the enzyme tyrosinase is needed to produce the dark pigment melanin and <span style="font-weight: bold;">Burmese cats</span> have a mutant form that is only active at low temperatures, resulting in color appearing only on the cooler ears, tail and paws.<br /><br />A completely inactive gene for tyrosinase is found in albino cats, which therefore lack all pigment. Hair length is determined by the gene for fibroblast growth factor 5, with inactive copies of this gene causing long hair.<br /><br />The Cat Genome Project, sponsored by the Laboratory of Genomic Diversity at the U.S. National Cancer Institute Frederick Cancer Research and Development Center in Frederick, Maryland, aims to help the development of the cat as an animal model for human hereditary and infectious diseases, as well as contributing to the understanding of the evolution of mammals.<br /><br />This effort led to the publication in 2007 of an initial draft of the genome of a Abyssinian cat called Cinnamon. The existence of a draft genome has led to the discovery of several cat disease genes, and even allowed the development of cat genetic fingerprinting for use in forensics.<p><sup id="cite_ref-76" class="reference"><a href="http://en.wikipedia.org/wiki/Cat#cite_note-76"><span></span><span></span></a></sup></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-89934658634191712022009-11-03T15:28:00.000-08:002009-11-03T17:41:30.516-08:00Cat Senses<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_Ber2QzIQMms/SvDbD9K2KnI/AAAAAAAABOI/RhkjHXMtFzM/s1600-h/White+Cat.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 348px; height: 326px;" src="http://4.bp.blogspot.com/_Ber2QzIQMms/SvDbD9K2KnI/AAAAAAAABOI/RhkjHXMtFzM/s400/White+Cat.jpg" alt="" id="BLOGGER_PHOTO_ID_5400056814223370866" border="0" /></a><br /><span style="font-weight: bold;">Cats</span> have excellent <span style="font-weight: bold;">night vision</span> and can function at only one-sixth the light level required for human vision. This is partly the result of cat eyes having a tapetum lucidum, which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light.<br /><br />Another adaptation to dim light is the large pupils of cats' eyes. Unlike some big cats, such as tigers, domestic cats have slit pupils.<br /><br />These slit pupils can focus bright light without chromatic aberration, and are needed since the domestic cat's pupils are much larger, relative to their eyes, than the pupils of the big cats.<br /><br />Indeed, at low light levels a cat's pupils will expand to cover most of the exposed surface of its eyes. However, <span style="font-weight: bold;">domestic cats</span> have rather poor color vision and can only see two colors: blue and green, and are less able to distinguish between red and green, although they can achieve this in some conditions.<br /><br /><p></p>Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than either dogs or humans, detecting frequencies from 55 Hz up to 79 kHz, a range of about 7 octaves; while humans can only hear from 31 Hz up to 18 kHz, and dogs hear from 67 Hz to 44 kHz, which are both ranges of about 6 octaves.<br /><br />Cats do not use this ability to hear ultrasound for communication but it is probably important in hunting, since many species of rodents make ultrasonic calls. Cats' hearing is also extremely sensitive and is among the best of any mammal,being most sensitive in the range of 500 Hz to 32 kHz.<br /><br />This sensitivity is further enhanced by the cat's large movable outer ears (their pinnae), which both amplify sounds and help a cat sense the direction from which a noise is coming. Cats have an acute sense of smell, which is due in part to their well-developed olfactory bulb and also to a large surface of olfactory mucosa, in cats this mucosa is about 5.8 cm2 in area, which is about twice that of humans and only 1.7-fold less than the average dog.<br /><br />Cats respond strongly to the smell of nepetalactone, a compound found in catnip, and can detect this substance at less than one part per billion. Cats are also sensitive to pheromones such as 3-Mercapto-3-methylbutan-1-ol, which they use to communicate through urine spraying and marking with scent glands.<br /><br />Due to a mutation in an early cat ancestor, one of two genes necessary to taste sweetness may have been lost by the <span style="font-weight: bold;">cat family</span>. Their taste buds instead respond to amino acids, bitter tastes and acids. To aid with navigation and sensation, cats have dozens of movable vibrissae (whiskers) over their body, especially their face.<br /><br />These provide information on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.<br /><sup id="cite_ref-52" class="reference"><a href="http://en.wikipedia.org/wiki/Cats#cite_note-52"><span></span></a></sup>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-31475006886242838132009-10-29T20:39:00.000-07:002009-10-29T20:56:43.611-07:00Cats ( part 2 )<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_Ber2QzIQMms/Supj8dPE5UI/AAAAAAAABOA/H6FGd6eE_VE/s1600-h/predator.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 400px; height: 337px;" src="http://2.bp.blogspot.com/_Ber2QzIQMms/Supj8dPE5UI/AAAAAAAABOA/H6FGd6eE_VE/s400/predator.jpg" alt="" id="BLOGGER_PHOTO_ID_5398236993648125250" border="0" /></a><br />The Felids are a rapidly evolving <span style="font-weight: bold;">family of mammals</span> that share a common ancestor only 10-15 million years ago. Within this family, <span style="font-weight: bold;">domestic cats</span> (Felis catus) are part of the genus Felis, which is a group of small cats containing seven species.<br /><br /><br />Members of the genus are found worldwide and include:<br /><ul><li><span style="font-weight: bold;">Jungle Cat</span> (Felis chaus) of southeast Asia, </li><li><span style="font-weight: bold;">African Wildcat</span> (Felis silvestris lybica), </li><li><span style="font-weight: bold;">Chinese Mountain Cat</span> (Felis silvestris bieti) </li><li><span style="font-weight: bold;">Arabian Sand Cat</span> (Felis margarita).</li></ul><br />All the cats in this genus share a common ancestor that probably lived around six million years ago in Asia. Although the exact relationships within the Felidae are still uncertain,both the Chinese Mountain Cat and the African Wildcat are close relations of the domestic cat and are both classed as subspecies of the Wildcat Felis silvestris.<br /><br />As domestic cats are little altered from wildcats, they can readily interbreed. This hybridization may pose a danger to the genetic distinctiveness of wildcat populations, particularly in Scotland and Hungary.<br /><br />The <span style="font-style: italic;">domestic cat</span> was first classified as Felis catus by Carolus Linnaeus in the tenth edition of his Systema Naturae of 1758. However, due to modern phylogenetics, domestic cats are now usually regarded as another subspecies of the Wildcat Felis silvestris. This has resulted in mixed usage of the terms, as the domestic cat can be called by its subspecies name, Felis silvestris catus.<br /><br />Wildcats have also been referred to as various subspecies of F. catus, but in 2003 the International Commission on Zoological Nomenclature fixed the name for Wildcats as F. silvestris.<br /><br />The most common name in use for the domestic cat remains F. catus, following a convention for domesticated animals of using the earliest (the senior) synonym proposed. Sometimes the domestic cat is called Felis domesticus, although this is not a valid scientific name.<br /><br />Cats have either a mutualistic or commensal relationship with humans. However, in comparison to some other domesticated species, such as dogs, cats have not undergone major changes during the domestication process, as the form and behavior of the domestic cat are not radically different from those of wildcats and domestic cats are perfectly capable of surviving in the wild.<br /><br />Several natural behaviors and characteristics of Wildcats may have preadapted them for domestication as pets. These traits include their small size, social nature, obvious body language, love of play and relatively high intelligence. All the small Felids may also have an inborn tendency towards tameness.<br /><br />There are two main models for how cats were domesticated. In one model, people deliberately tamed cats in a process of artificial selection, as they were useful predators of vermin. However, some theorists find this implausible, because there may have been little reward for such an effort: cats do not carry out commands and, although they do eat rodents, other species such as ferrets or terriers may be better at controlling these pests.<br /><br />The alternative idea is that cats were simply tolerated by people and gradually diverged from their 'wild' relatives through natural selection, as they adapted to an agricultural environment.<br /><sup id="cite_ref-21" class="reference"><a href="http://en.wikipedia.org/wiki/Cats#cite_note-21"><span></span></a></sup>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-65065664278318900612009-10-22T07:10:00.000-07:002009-10-22T07:19:00.518-07:00Cat<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_Ber2QzIQMms/SuBpvdc41nI/AAAAAAAABNg/ghR8qQAX3Jk/s1600-h/cat.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 400px; height: 317px;" src="http://4.bp.blogspot.com/_Ber2QzIQMms/SuBpvdc41nI/AAAAAAAABNg/ghR8qQAX3Jk/s400/cat.jpg" alt="" id="BLOGGER_PHOTO_ID_5395428617670415986" border="0" /></a>The cat (Felis catus), also known as the domestic cat or housecat to distinguish it from other felines and felids, is a small carnivorous mammal that is valued by humans for its companionship and its ability to hunt vermin and household pests.<br /><br />It has been associated with humans for at least 9,500 years and is currently the most <span style="font-weight: bold;">popular pet</span> in the world.<p><br /></p> <p></p>A skilled predator, the cat is known to hunt over 1,000 species for food. It can be trained to obey simple commands. Individual cats have also been known to learn on their own to manipulate simple mechanisms, such as doorknobs and toilet handles.<br /><br />Cats use a variety of vocalizations and types of body language for communication, including meowing, purring, "trilling", hissing, growling, squeaking, chirping, clicking, and grunting. They are also bred and shown as registered pedigree pets.<br /><br />This hobby is known as "cat fancy". Until recently the cat was commonly believed to have been domesticated in ancient Egypt, where it was a cult animal. However, in 2004, a domesticated cat that was buried 9,500 years ago was discovered in Cyprus, and a study in 2007 found that the lines of descent of all house cats probably run through as few as five self-domesticating African Wildcats (Felis silvestris lybica) circa 8000 BC, in the Near East.<br /><br /><p></p>The word cat derives from Old English catt, which belongs to a group of related words in European languages, including Welsh cath, Spanish gato, Basque katu, Byzantine Greek kátia, Old Irish cat, German Katze, and Old Church Slavonic kotka.<br /><br />The ultimate source of all these terms is Late Latin catus, cattus, catta "domestic cat", as opposed to feles "European wildcat". It is unclear whether the Greek or the Latin came first, but they were undoubtedly borrowed from an Afro-Asiatic language akin to Nubian kadís and Berber kaddîska, both meaning "<span style="font-weight: bold;">wildcat</span>".<br /><br />This term was either cognate with or borrowed from Late Egyptian čaus "jungle cat, African wildcat" (later giving Coptic šau "tomcat"), itself from earlier Egyptian tešau "female cat" (vs. miew "tomcat").The term puss (as in pussycat) may come from Dutch poes or from Low German Puuskatte, dialectal Swedish kattepus, or Norwegian pus, pusekatt, all of which primarily denote a woman and, by extension, a female cat.<br /><br />A group of cats is referred to as a "clowder", a male cat is called a "tom" (or a "gib", if neutered), and a female is called a "molly" or "queen". The male progenitor of a cat, especially a pedigreed cat, is its "sire", and its female progenitor is its "dam".<br /><br />An immature cat is called a "kitten" (which is also an alternative name for young rats, rabbits, hedgehogs, beavers, squirrels and skunks). In medieval Britain, the word kitten was interchangeable with the word catling. A cat whose ancestry is formally registered is called a pedigreed cat, purebred cat, or a show cat.<br /><br />In strict terms, a purebred cat is one whose ancestry contains only individuals of the same breed. A pedigreed cat is one whose ancestry is recorded, but may have ancestors of different breeds. Cats of unrecorded mixed ancestry are referred to as domestic longhairs and domestic shorthairs or commonly as random-bred, moggies, mongrels, or mutt-cats.<br /><p><sup id="cite_ref-Driscoll_3-1" class="reference"><a href="http://en.wikipedia.org/wiki/Cats#cite_note-Driscoll-3"><span></span></a></sup></p>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-3295277288257323302009-10-07T07:30:00.000-07:002009-10-15T11:39:17.222-07:00Cat Food ( part 2 )<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_Ber2QzIQMms/StdsQkxAKbI/AAAAAAAABNI/3EdHJc9QTjo/s1600-h/Canned+cats+food.jpg"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 400px; height: 300px;" src="http://4.bp.blogspot.com/_Ber2QzIQMms/StdsQkxAKbI/AAAAAAAABNI/3EdHJc9QTjo/s400/Canned+cats+food.jpg" alt="" id="BLOGGER_PHOTO_ID_5392898110802373042" border="0" /></a><br /><p></p>Since the occurrence of BSE infection through contaminated meat and bone meal, the use of meat meal in <span style="font-weight: bold;">pet foods</span> has been prohibited in parts of the world (Japan and France) but is still common practice in other parts (USA).<br /><br />Comparative studies conducted by Japanese researchers have shown that meat meal is superior to the other protein meal sources in terms of dry-matter digestibility and nutritional value for cats, while <span style="font-weight: bold;">corn gluten meal</span> is the least nutritional.<br /><br />The same studies showed that <span style="font-weight: bold;">cats fed</span> with these dry food diets excreted alkaline urine. Urine pH has been implicated in the formation of struvite crystals in feline urolithiasis, and many dry food manufacturers address this by adding urine-acidifying ingredients to their food.<br /><br />However, this practice may lead to the formation of calcium oxalate stones, therefore water intake rather than urine pH appears to be the most crucial diet related factor for the prevention and treatment of feline stones.<br /><br /><span style="font-weight: bold;">Canned or wet food</span> (75-78% moisture) generally comes in common can sizes of 3 oz (85 g), 5.5 oz (156 g), and 13 oz (369 g). It is also sold in foil pouch form by some manufacturers. Owners and veterinarians who recommend a diet consisting largely or entirely of canned, homemade or raw cat food point to higher water content of such food and the increased total water consumption in comparison to a dry food diet as an important health benefit.<br /><br />Wet food also generally contains significantly less grain and other carbohydrate material. Many foods are made with fish, however an excessive consumption of fish (which contains high levels of unsaturated fatty acids) can cause yellow fat disease.<br /><br />In comparison to dry food, canned food is thought to either help treat or noticeably reduce the likelihood of numerous health issues including urinary tract disorders, diabetes, chronic renal failure, constipation (sometimes leading to megacolon), and obesity.<br /><br />Canned cat foods in pop-top containers may play a role in the development of hyperthyroidism in cats. This may be due to bisphenol A used in the pop-top can coating leaching into the food, so it is suggested to place unused food in reusable containers to prevent contamination.<br /><h3><span class="mw-headline" id="Prescription_food"></span></h3><br /><sup id="cite_ref-7" class="reference"><a href="http://en.wikipedia.org/wiki/Cat_food#cite_note-7"><span></span></a></sup>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-3491042788521404272009-10-07T07:22:00.000-07:002009-10-07T07:33:07.221-07:00Cat Food<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_Ber2QzIQMms/SsymlDFj27I/AAAAAAAABM4/aWJyMG8ocrk/s1600-h/dry+cat+food.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 400px; height: 266px;" src="http://2.bp.blogspot.com/_Ber2QzIQMms/SsymlDFj27I/AAAAAAAABM4/aWJyMG8ocrk/s400/dry+cat+food.jpg" alt="" id="BLOGGER_PHOTO_ID_5389866009469639602" border="0" /></a><br /><b>Cat food </b>is formulated to address the specific nutritional requirements of cats. Although cats are obligate <span style="font-weight: bold;">carnivores</span>, most <span style="font-weight: bold;">commercial cat food</span> contains both animal and plant material, supplemented with vitamins, minerals and other nutrients.<br /><br />An important nutrient is the amino acid derivative taurine, as cats cannot synthesize the compound. Cats fed a taurine-deficient dog food may develop retinal degeneration and go blind.<br /><br />Most store-bought cat food comes in either dry form, also known in the US as kibble, or wet canned form. Some manufacturers sell frozen raw diets and premix products to cater to owners who feed raw.<br /><span style="font-weight: bold;"></span><br /><p></p><span style="font-weight: bold;">Dry food</span> (8-10% moisture) is generally made by extrusion cooking under high heat and pressure. Fat may then be sprayed on the food to increase palatability, and other minor ingredients, such as heat-sensitive vitamins, which would be destroyed in the extrusion process, may be added.<br /><br />Major brand-name <span style="font-weight: bold;">dry cat food</span> manufacturers often use primarily grain-based ingredients with animal protein by-products or animal digest to cut cost. Higher end foods offered as 'premium', 'natural' or 'holistic' formulas contain less or no grain, and a higher percentage of animal protein.<br /><br />However, grain-free dry diets still contain carbohydrates, from sources such as potato or tapioca. The starch in those ingredients allows the kibble to hold its shape. Cats have no metabolic need for carbohydrates as the feline system prefers to create glucose from protein.<br /><br /><span style="font-weight: bold;">Dry cat food</span> has an advantage over wet in convenience and price – besides usually being significantly cheaper, dry cat food can also be left out for the cat to eat at will over the course of several days, whereas canned or raw cat food spoils or becomes unappetizing after several hours.<br /><br />It should be noted, however, that even dry food, since it is sprayed with fats as noted above, becomes rancid and stale as it oxidizes. Using a free feeding practice can also contribute to overeating, and ultimately obesity. Dry food is recommended by some based on the idea that cats break apart dry foods with their teeth, which causes the food to scrape off dental calculus. The degree of benefit this provides has been disputed in recent years.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-5740819718656212358.post-16697860770862321482009-09-29T15:41:00.000-07:002009-09-29T15:48:16.423-07:00Protein For Your Cat<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_Ber2QzIQMms/SsKOpJNm--I/AAAAAAAABMY/3LGdSIamDWo/s1600-h/cat+protein+metabolizm.htm"><img style="margin: 0pt 0pt 10px 10px; float: right; cursor: pointer; width: 356px; height: 262px;" src="http://3.bp.blogspot.com/_Ber2QzIQMms/SsKOpJNm--I/AAAAAAAABMY/3LGdSIamDWo/s400/cat+protein+metabolizm.htm" alt="" id="BLOGGER_PHOTO_ID_5387024941787315170" border="0" /></a><br /><span style="font-weight: bold;">Protein</span> is one of the basic <span style="font-weight: bold;">building blocks </span>of any body, whether it's a cat's or a human's. Hair and nails are mostly made of protein. It's used to build and repair tissues as well as make enzymes, hormones, and other body chemicals.<br /><br /><br /><p>Along with fat and carbohydrate, protein is a "macronutrient," meaning that both animals and humans need relatively large amounts of it to provide the bulk of their energy.

The <span style="font-weight: bold;">pet food recall </span>sent many spinning.<br /><br />Most <span style="font-weight: bold;">pet owners</span> are aware that pet food manufacturers are required by law to list all of the product ingredients in order of weight. While that is helpful, an organized checklist is more useful when shopping. Here are some guidelines from top animal food experts.<br /><br /><br /><b>Cat Food Ingredients in Order of Importance</b><br /><br /><b>1. Proteins</b><br /><br />LOOK FOR: Meat or fish named on the label with words like--chicken, turkey, lamb, beef, herring, salmon, etc. Also acceptable are concentrated named meat proteins like--chicken meal, turkey meal, lamb meal, herring meal, etc.<br /><br />WHY? Cats are what scientists call "obligate carnivores". This means that they are designed to eat a meat diet. When you're choosing a food for your cat, you want it to have all the available nutrients to provide for good energy, strong muscle tone and a<br />stable immune system so the meat protein source should be primary.<br /><br />AVOID: Unnamed food ingredients with words like--poultry by products, meat and bone meal, meat meal, poultry meal, animal digest, etc. Also avoid protein fillers like--corn gluten meal, wheat gluten, egg product meal, soybean meal, wheat germ meal.<br /><br />TIP: If you look at a cat food label and group all the grain ingredients together, they are often more primary than the meat pictured by manufacturers. This disguises protein ingredients that are inferior, portraying them as nutritious.<br /><br />REASON: Cat foods containing by-products, meat and bone meal or non-specific, generic meat meals are often rejected leftovers from the human food chain. That means they can contain "4-D" nutrient-deficient animal protein sources such as:<br /><br />* Dead animals (including meat with sodium pentobarbital, the most common euthanasia drug though industry sources deny they use dead dogs and cats, however there are no laws or regulations against it).<br /><br />* Dying animals (including those that FDA meat inspectors reject for the human food chain plus dying animals from zoos and pet farms).<br /><br />* Diseased animals (according to federal meat inspection regulations, fuel oil, kerosene, crude carbolic acid, and citronella can be used to denature diseased meat before rendering).<br /><br />* Disabled animals (including those who are too weak to walk due to disease or malnutrition).<br /><br /><b>2. Carbohydrates and Vegetables</b><br /><br />LOOK FOR: Whole grains like brown rice and barley or starches like whole potatoes or sweet potatoes. Whole fruits and vegetables like carrots, tomatoes, alfalfa, apples, cranberries, etc.<br /><br />WHY? These whole grains and starches are actually digestible by cats providing a good source of energy. The whole fruits and veggies provide an excellent source of fiber plus natural occurring vitamins and minerals.<br /><br />AVOID: Vegetable proteins and gluten, which are indigestible and cause allergies for cats, are made from refined flours, wheat, mill runs, brewer's rice, etc. Also watch out for processed fruits and vegetables like dehydrated potatoes, tomato pumice and alfalfa meal.<br /><br />REASON: Vegetable proteins, especially soybean meal protein, have become favorites of pet food manufacturers because they are cheap sources of protein, giving them bigger profits and making it appear that cats are getting good protein. Glutens made from flours are merely cheap binders or "glue" in pet foods. Both sources can result in severe nutritional deficiencies.Unknownnoreply@blogger.com0
