Cats are very emotional, but they don't often show their feelings too much.
We'll tell you how to tell if your mustachioed pet is angry.
The first thing an angry cat does is raise and fluff up its tail. This means aggression and threat.
An irritated cat may also move its tail sharply from side to side.
When a cat is preparing to defend itself or attack, it arches its back.
Also, ears and whiskers pressed to the head, dilated pupils, and a glassy look may indicate that the cat is ready to attack.
