Usually, when a cat bites, it is suggested that the owner take the following measures to educate the cat: first, when the cat bites, the owner should gently open the cat's mouth, and then raise the volume of speech to make the cat feel that he is wrong. You can also pat the cat on the cheek with your fingers to let it know that this is not allowed. Secondly, the owner can hold the cat's favorite snacks in one hand and then put the other hand in front of the cat's mouth. Cats can reward snacks if they don't bite their owners. If the cat bites the owner, the owner will put away the snacks. After repeated times, the cat will know that biting is wrong, but the owner needs to pay attention to his own safety during training. It's best to wrap gauze or gloves around his hands. Furthermore, if the cat bites people or other things when changing teeth or when the teeth are uncomfortable, the owner should prepare some grinding sticks, dried fish and meat strips for the cat to grind their teeth.
