Generally, cats within 6 months can be corrected by training, and those over 6 months are not easy to correct. The owner should be patient enough.
1, 2 to 6 months, prepare a cat scratch board. You can buy corrugated paper online, or you can find a board wrapped with hemp rope and fix it on the ground or wall where the cat can reach, so as to satisfy its nature of grinding claws and prevent it from catching people and biting people because of irritability.
2. Establish conditioned reflex
When a kitten bites a person, its owner should gently hold the skin behind its neck and fix it so that it cannot escape. Hit it on the hind leg with a thin stick. If it hurts but doesn't hurt your bones, show it your wound once and repeatedly establish conditioned reflex. When the cat does well, reward it, such as delicious food or touching praise. Cats are smart enough to understand what you mean.
