Well he is a 2 year old Maine Coone. Problem is that he has attacked my resident once before and caused him a big abscess wound on his back. They are both male, same age, but the new cat has claws and resident cat does not. Resident cat is very laid back and doesnt really want to play. New kitty wants him to play. I feel like the more I play with him the more worked up he gets and if I dont play with him he is more tame??
