So we got a the cutest kitten ever on Saturday, he's 8 weeks old. We already have a 2 year old kitty. Both are male. The 2 year old has been neutered at 4 months and the new kitten will be done when the vet will do him. Anyway the 2 year is petrified of the new kitten. He was just running away from him, he is now spending more time around him but he is growling at him and he has tapped him on his head a couple of times. Does this sound like progress at all? We keep them separated over night and then supervised throughout the day. I've tried to keep my older cats routine as normal as possible.
