Aggression (Towards …)

[tabby title="People"]


If your cat is aggressive toward people, the first step is to identify the type and cause of the aggression. Aggression toward strangers or visitors is most often fear-based, so see the links for helping your cat feel more comfortable around people. If your cat attacks you when you move him away from another cat (or a window where he can see another cat), this redirected aggression is really a symptom of stress around other cats, so see the links on aggression between cats. If your cat sometimes scratches or bites you when you are petting or playing with him, this usually responds well to some relatively simple management and training
