The reasons why cats always lick their fur:

1. The most basic reason for cats to lick their fur is to clean their bodies. Cats love to be clean and have mysophobia.

2. Cats lick their fur to relieve their nervousness and stress.

3. Cats suffer from skin diseases. If there are parasites, the skin will be very itchy, and the cat will not be able to help but lick and bite that skin crazily.

4. When the ambient temperature affects the cat, the cat may lick its fur to regulate its body temperature.

5. Cat licking is also a kind of obsessive-compulsive disorder. It’s okay for a cat to lick normally. If a cat goes through something, it needs to keep licking to stay calm.
