Cat behavior encompasses the actions and reactions displayed by a cat in response to various stimuli and events. Cat behavior includes body language, elimination habits, aggression, play, communication, hunting, grooming, urine marking, and face rubbing. It varies among individuals, colonies, and breeds. Communication and sociability can vary greatly among individual cats. In a family with many cats, the interactions can change depending on which individuals are present and how restricted the territory and resources are. One or more individuals may become aggressive: fighting may occur with the attack, resulting in scratches and deep bite wounds. Source: Wikipedia (en)
