A cat’s personality is shaped by both natural factors and acquired environment. A cat’s personality is affected to a certain extent by genetic factors. Different types of cats have different personality tendencies. For example, large cats, Maine Coon cats, are usually relatively calm. Gentle, while Bengal cats tend to be more lively and active, and the father's personality will be passed on to the kittens.

A cat's growth environment and interaction with people will all affect the cat's personality. For example, living in an unhygienic environment or often facing Dangerous cats may become wary.

If the cat owner can give the cat enough care and companionship to make them feel at ease and comfortable, then the cat's personality may become stable and friendly.
