A cat will get angry if it wakes up from sleep, and may scratch its owner to express dissatisfaction. If the cat's sleep is frequently disturbed, the cat may become vengeful and retaliate against the owner by defecating everywhere, and may also become irritable. It is recommended not to disturb the cat's sleep at will. Place the cat's nest in a warm and quiet environment to prevent sounds such as thunder and firecrackers from frightening the cat, affecting the cat's sleep, and causing bad phenomena. There may be a small number of cats who will not be angry.

Signs of an angry cat:

1. Wagging its tail. A cat's tail is the part where it expresses emotions. When a cat is angry, its tail will shake rapidly from left to right, and its body will be depressed at this time.

2. Narrowing of pupils. When a cat's pupils narrow, it means it is angry, especially when its eyes become sharp at this time.

3. The body is arched and hairy all over. When a cat is threatened or someone invades, it will arch its body and erupt its fur as a warning and to warn the intruders to retreat.

4. Airplane ears appear. Usually when cats fight, their ears will be pressed back. This is called airplane ears. They maintain this fighting state with each other.

5. Raise your beard. A cat’s whiskers can also be used to express its mood. When a cat’s whiskers are raised, it means the cat is angry.
