I have a 9 year old persian male. Over the last year he has become aggressive toward anything that is in my bedroom, besides me while I am sleeping. He has always slept on the bed and has not had issues before this with my girlfriend or the other cat in the home. If my girlfriend and I go to sleep at the same time it is fine, but if I am already sleeping and she comes in from work or just watching tv, he will growl at her and on a few occasions has charged her. He has never physically scratched or bit her. With the other cat we have in the house it is worse. If the other cat comes in, expect a catfight and chasing. It is to the point where I will just keep the door shut to keep the other cat out. I have to wait for my girlfriend to go to bed so we go at the same time. I don't know what to think of it. I have tried keeping the my persian out of the bedroom but he will nonstop meow, scratch and whine at the door until he is let in. Trust me I did that for 2 weeks and it just seemed to stress him out. Any suggestions? I have had him since he was a kitten and under all other circumstances my persian is loving with my girlfriend and the other cat.
