i have had my cat for 7 years, he’s an indoor cat weighing in at 20 lbs. and is neutered, he has always played roughly and been aggressive at times, he gets angry and will attack us if we move him from a chair we want to sit in or if we don’t let him in an off limits room. He also targets one of my other cats from time to time for no apparent reason. I’m not sure what to do with him, we’ve had him since he was 4 weeks old and his aggressive behavior can be frightening as he breaks the skin with bites and deep scratches. He’s never been a lap cat and tolerates limited petting but does love us, he rubbes up to us and follows us room to room to be with us. He sleeps in my bed with no aggression also. I’m at my whits end with this boy, I’ve had cats my whole life but never one so aggressive , any and all suggestions greatly appreciated.
