You're right treybabe!

Start now, don't wait until he is older!
Another thing I have heard is to relax your hand (or whatever), then they naturally stop. A cats instinct is to keep fighting/attacking if you continue to struggle or move because it's like the cat is going after some prey &/or protecting itself. When you stop moving, it looses interest. AT THE SAME TIME SAY "NO!"

I did this with my now one year old kitty, and he is (almost) bite-free now


And, very important: DON'T play with him like that, even as a kitten. If you do, then they think it's okay, and develop the bad habit. It's cute and funny when they are little sometimes, but not worth it when they get older with big teeth & claws
