When kittens play, they are training for becoming the hunters that cats are by nature. Rabbit kicking (holding on with the forelimbs and striking out with the hind) and biting are normal extensions of this training. When your kitten plays with you, she will become excited and the play will often become rough. She may begin to bite or kick harder than you would like.
Play with her up to the point that she becomes too rough, and stop. Tell her firmly, “No.” With repetition, this action should put an end to the rough behavior. Your kitten will begin to associate roughness with the end of playtime.
