He is about to be 9 months old and he like to play a lot with his teeth and that hurts my skin so much. I've been told that when he grows older his teeth will become dull but I just don't know when will that be!! Any advice?
I dont know this for certain, but I dont really think that your kitten's teeth ever will get dull. Cats are carnivorous animals. Their teeth are designed to be sharp. Perhaps you should see an animal behaviourist about training your kitten not to bite when playing. Or you could try to train him yourself. Good luck.
