ok so, i have a 3 year old neutered male cat and recently adopted a 6 month non-neutered male kitten. they get along for the most part. they play a lot with eachother, they chase eachother and play hide n seek. but occasionally when the 3 year old male is tired and doesnt want to play anymore, the kitten picks on him and bothers him. tommy (the 3 year old) tries to walk away/get away to rest. but the kitten wont leave him alone, my husband thinks the kitten is being 'aggressive' with tommy. i thought the kitty is just a kitty and typically full of energy and just wants to play though tommy doesnt right now. i don't know. ive tried to play with them both with a feather to get rid of some of the energy off the kitten but once i stop, the kittens attention is back on tommy and hes picking on him again. i tried to put kitten in other room for a while to calm him down, it doesnt always work., what do you think? any suggestions? my husband also thinks its something to do with the kitten being non-neutered and its a type of authority thing. i really dont know. what do you think?
