I already had an 8 year old Abyssinian male and just got a male Abyssinian kitten. For the first few weeks they were fine. Now the kitten is 5 months old and there is constant fighting and screaming. It is the kitten who is the aggressor and will not leave the other cat alone. He even bothers him while he's in the litter box!! I probably should not have gotten another male, but the breeder said it didn't matter. Now what do I do? I keep breaking up the fights, afraid one will get hurt. They end up rolling around on the floor biting each other, but so far no injuries. The older cat is the one who screams. Could they be just play fighting? I only have a one bedroom apartment and to separate them is not doable. The kitten refuses to be locked up and practically breaks the door down! HELP.
