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.
