I got a kitten about 4 months ago named Chester. It was around 6 weeks at the time. I have a 4 year old Pug and a 12 year old cat. He is the most aggressive cat I have ever had and absolutely can't be deterred from terrorizing my older cat. The pug likes to play with him most of the time so that isn't a huge problem (although Chester still "nurses" on Chloe). Chester doesn't respond to water spraying or yelling or "time outs". I have just never had a cat that needed discipline. I have had him declawed on the front because he was tearing us up climbing our legs and I did have him castrated this week hoping that might help. He also bites quite a bit but I can handle that. I have had several kittens in my life but I have never had a cat that I could absolutely not do anything with. I have tried playing with him alot hoping that might wear him out but he rests for 5 minutes and then he is off again. My husband wants to get rid of him but I am not like that. I have never given a pet away that I have taken responsibility for. As it is now, I have to keep the two cats separated by dividing the time each is locked in my room. I have tried letting them work it out themselves but Chester just climbs on top of my older cat and just chews and bites her. I know he is trying to play but I can't let him terrorize my older cat. Any advice how I can get him to calm down?
I won't get on a soap-box about declawing (that's a personal choice and I agree that sometimes there seems like no other way to stop the clawing) BUT sometimes it actually increases aggression and biting because claws are their instinctive defense and it makes them resort to biting instead. Although I did lose quite a bit of blood while my babies were learning that I was not a climbing tree. I just kept their claws trimmed and now they know better. He should eventually grow out of it but I just read a pretty good article on petplace.com about redirecting the aggression with toys, etc. If you type "cat aggression" into the search box on that website, a bunch of articles come up that may be helpful.
