Instructions
Provide your kitten with toys instead of your hands. Anytime any member of your family plays with the cat, they should use some sort of toy. This will teach the cat to attack toys and will help protect your hands from bites and scratches.
Learn to recognize signs of discomfort in your kitten. Not every cat enjoys being held or played with, and some cats may lash out once they have had enough. If your kitten begins hissing, arching its back or squirming in your grasp, it is time to give it some space.
End any play as soon as the kitten becomes overly rough. If the kitten bites or scratches you, simply stop playing and leave the room. The idea is to show the kitten that once he behaves in a certain way, the game will end.
Act consistently. If you want to end aggressive play, everyone who interacts with the cat must take the same approach at all times. If it is not okay for the kitten to bite or scratch your children, he cannot bite or scratch you or your friends. If everyone acts the same way, the kitten will learn much more quickly.
How to Tame an Aggressive Kitten
Kittens naturally learn the differences between fun and aggressive play when they wrestle with their littermates. Young kittens quickly show each other how to differentiate between a friendly nibble and a fierce bite, as well as how to control the strength of their claws. Unfortunately, kittens that are separated from the litter at a very young age may not have received this natural training, making them overly rough and sometimes aggressive. Toning down your kitten's aggression can be frustrating, but is possible if you are willing to invest the necessary time.
