Cat owners sometimes have difficulty understanding why their cats, who seem to be friendly and content one minute, may suddenly bite and scratch them the next.
Aggressive behaviours are part of the normal behavioural patterns of almost any animal species.
Do not want to be petted any longer. View certain people as intruders in their territory. Cat bites are seldom reported, but may occur more frequently than do bites from dogs. Aggressive cats can be dangerous, so attempting to resolve a cat aggression problem often requires assistance from a professional who is knowledgeable about cat behaviour. Play in cats incorporates a variety of behaviours such as exploratory, investigative, and predatory behaviour.
