Methods to train an American wirehaired cat not to bite:

1. When the cat bites, pat its head gently with your hand and say loudly Scold and stop it in time to make it fearful. If it still bites, pat it a few more times and scold it loudly to scare it.
2. If the cat is just playing with you and biting your hand, try not to tease it with your hands at ordinary times. Let it develop a good habit. You can use toys such as cat teasing sticks to interact with it.
3. If a kitten bites, consider whether it needs to grind its teeth. You can prepare a molar stick for it to satisfy its instinctive need for biting.
4. Owners who have the conditions can keep two cats at the same time. When the cats have playmates, their tempers will become better and their interest in attacking people will be greatly reduced.
5. Put your hand next to the cat's mouth. If it doesn't bite, you can reward it and slowly guide it so that it won't bite again.
