Cats that bite people often may grind their teeth. There are usually two reasons for biting. One is that they need to grind their teeth, and the other is that they are not used to biting people. It depends on the situation. When a cat often bites its fingers, toes and other parts, it may be grinding its teeth. The teething period usually starts from 7 to 8 months and lasts for a long time. It is recommended that owners prepare special teething toys for cats.

The reasons why cats keep biting people:

1. The need to grind teeth. When a cat is in the teething period, its teeth will be itchy and they need to bite something to relieve the itching of the teeth.

2. Express love. When a cat wants to express its affection for its owner, it will bite the owner with its teeth.

3. Nature. It is a cat’s nature to like to bite, and biting is a learning process of hunting behavior.

4. Self-protection. Cats are sensitive and suspicious, and are afraid of contact with people. When people come close to them, they will attack people to protect themselves.

5. Physical abnormalities. The cat has physical abnormalities and feels pain or discomfort.

6. Maternal instinct. Mother cats will protect their kittens because of their maternal instinct, and even people they trust may be bitten.
