Cats feed on small prey, primarily birds and rodents. Feral cats and house cats that are free-fed tend to consume many small meals in a single day, although the frequency and size of meals varies between individuals.

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.

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.

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".

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.

One poorly understood element of cat hunting 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.

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.

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.

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.

Cats are known for their fastidious cleanliness, spending many hours licking their coats.The cat's tongue has backwards-facing spines about 500 micrometres long, which are called papillae. 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.

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.

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.

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.

Fighting cats 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.

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.

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.

Free-ranging cats are active both day and night, although they tend to be slightly more active at night. The timing of cats' activity is quite flexible and varied, which means that house cats may be more active in the morning and evening (crepuscular behavior), as a response to greater human activity at these times.


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.

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 cat nap".

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.

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.

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.

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.

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.

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.

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.

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.
