Cats biting people’s hands may be because they are in the period of teeth replacement, so they want to relieve the discomfort by biting their owners’ hands. Secondly, it may be because the owner often plays with the cat with his hands, so the cat treats human hands as toys to bite. In addition, when cats feel hungry, out of conditioned reflex, they will also bite their hands to ask for food from their owners. Finally, when a cat feels uneasy or scared, if the owner approaches it rashly, it may be accidentally injured. Therefore, when a cat bites a person's hand, the owner can first observe the cat's behavior and expression to further understand its emotional state and needs, and then take targeted measures.

1. In the teeth changing period

Cats will start to change their teeth when they are 3-4 months old. At this time, their mouths may feel pain and discomfort, and they need to bite and chew to relieve it. Therefore, the cat may bite the owner's hand or chew sofas, stools and other items. In order to help cats relieve their discomfort, owners can provide them with some chewable toys or teething sticks, and gradually correct their hand-biting behavior.

　2. Treat people’s hands as toys

If the owner usually likes to tease the cats with their hands, then over time they will treat the owner's fingers as prey or toys, which will lead to hand biting. Therefore, in order to avoid this situation, it is recommended that owners use special cat toys, such as cat teasing sticks, small balls, etc., to interact with cats. At the same time, owners should also take timely measures to correct their wrong behaviors, such as biting hands, feet, and sofas.

　3. Want to eat

Since the owner usually places food for the cat with his hands, the cat may form a conditioned reflex over time, thinking that the owner's hands are the source of food. Therefore, when a cat feels hungry, it will bite its hand to indicate to its owner that it needs food. In this regard, the owner can put some food and clean water for the cat to see if it has such needs.

　4. Feeling uneasy or afraid

When a cat feels uneasy or afraid, it may bite or hold its hand to protect itself or seek comfort. This usually occurs when the cat is in a strange environment, has contact with strangers, or feels threatened. Therefore, when a cat is frightened, it is recommended that the owner should not approach it easily to avoid being accidentally injured by the cat.
