1, loudly reprimand: loudly stop them when they accidentally bite, and loudly criticize their behavior to make them realize their mistakes.

2. Spray them with water: When they are hopeless, you can fill the kettle with water and spray them on their faces when they bite. Cats don't like water. If they are sprayed with water, they may shrink back and give up.

3. Punish them: after they bite again, punish them not to eat, or shut them in a small room when they are hungry, and let them out when they are soft, so that they know that they have done something wrong and won't dare next time.

4. Reduce the number of times you touch them with your hands: When teasing them, you can use a cat stick instead of your hands, so that they won't accidentally hurt people. It's best to cut their nails short to prevent injury.
