The behavior of our domestic cats is quite similar to that of their wild relatives. They are better at adapting to a self-sufficient life than other domestic pets. Kittens generally learn by watching their mothers or other cats, and following their examples. Undomesticated cats usually do not live in groups with other adult cats, but can form a certain bond with others through common food or shelter sources.
Indoor cats brought together at different times can live together peacefully when they each establish their own personal space. However, there is this problem of how to stop cats from spraying indoors. Kittens who are neutered at an early age tend to play and sleep with each other. They form a close bond and some even express a mourning period at the loss of a of one of their companions.
Young kittens who have been handled by children or adults at an early age are more prone to being people friendly as adults. Even older kittens or young adults who were not raised around people can become people friendly with them. It just takes a little patience and effort to get close to them.
Cats have a unique system of communication that humans can easily miss, for example, purring. Kittens can purr when they are a few days old. It usually occurs between mother and kitten during nursing. It is a sign of contentment, but can also happen when cats are sick or dying. House pets are not the only ones who purr, some of the big wild cats do too. Meows express several things. a long persistent meow is asking to be fed, issuing a complaint during nursing or rough play among litter kittens. Adult females in season meow with greater urgency and intensity. Growls, hissing and snarls are uttered during intense situations involving fights with other cats or the mothers warning of danger to her babies.
Body language reflects a cats feeling toward other cats or humans and signals either come closer or go away. A friendly greeting is indicated by the cat raising the tail high, rubbing its body against legs and hands of a human and turning its head to be scratched on top of the head and under the chin. Cats greet other cats by rubbing noses. An unfriendly gesture is identified by an erect body pointed forward with the head lowered. Its tail is twitching back and forth and the ears are pointed up but turned back. When cats are backed up, they bristle their fur, arch their backs and hiss and snarl, and bare their teeth. If they are provoked or feel threatened, they will attack.
Kittens begin to play with toys at around two weeks old. Pawing, chasing and biting develop their predatory skills. At about four weeks, they start to play with their mother or siblings. They roll around, bite and scratch each other and it can become too rough sometimes. However all of these traits are learning experiences to prepare them for adult life.
Needless to say, watching them performing all of these behaviors is an interesting and fun thing to do.
