How do i get my cat to stop play biting?

Have you ever seen My Cat from Hell on TV? That guy (Jackson Galaxy) has a web site that might be helpful. I'm not a cat person, so I have no real idea - with dogs, it would be about instilling bite inhibition in the way you play with them, but cats? Have minds of their own. I hear. :)

Redirect, redirect, redirect. Have a few designated biting toys on hand. Every nip gets redirected to the toy. It may never stop completely if he wasn't socialized as a kitten but this will definitely help.

Just get some toys that have an automatic thing to keep him busy he's a kitten he wants to play

He bites, he gets squirted
