Most of your kitten’s behaviors are learned from his mother. He will learn how to inhibit his bite from her (the mother) and littermates. So, separating him from his family too early is likely to breed unwanted behaviors and lead to undesirable nipping. Also, your kitten will learn good behavior from you.
In most cases, you can teach your kitten that rough play is not acceptable. When playing with him, and the play escalates too nippily, use these tips to make playtime more interesting and minimize injuries on your side or members of your family.
Hands and body parts
Try to stop your kitten from playing with your hands, feet, and other body parts. This will send a clear message that your fingers, as well as toes, aren’t ‘prey’ for pouncing.
When purchasing his toys, get him a fishing pole-type toys. Doing so will keep him away from your body, including your hands and body.
Something to wrestle
Ensure that your kitten has a thing to wrestle with. This can distract him from coming close to your hands and legs.
Also, encourage plays with "wrestling toys" through rubbing them (toys) against his belly when he seems to play rough—but ensure to put your hands away as soon as he accepts the toy.
No hitting, yelling
Never hit or yell at him when he tries to nip or pounce since this is likely to make him fearful –which can make your pet start avoiding you. Remember, the thing here is to train him, not to punish him.
Discouraging "bad" behavior
Playing is normal and it isn’t a bad behavior, however, you must set the rules straight for him: no biting. Also, ensure that everybody in your house is on the same page to optimize the effectiveness of your training.
Use the right training tools: Adaptive toys and spray bottles. Pay no attention when he is on the wrong side (tries to nip or bite).
