agression between 2 cats

Question
Hi Rosie! Thanx for hetting back to me so quick. Actually, I can't do that because of the apt. I live in. It just woldn't work out. It would be nice if we had a house with a sunroom or a basement.I like the idea of a coller that opens a door just for her. That's something to keep in mind. For now I heard something about pheramones, does that work? Why do you think it's just her he picks on? He also does not like my mom. He will walk right up to her, pretend he wants to be pet and then bite. Don't get me wrong, he's been my guardian angel for 12 years, and he has quite a personality. He's a great cat, but. Thanx for the info. TTYL

Hi Rosie!I appreciate any input you might have about this. I have 3 cats. Bruce is 12, abot 16 pounds, fixed, clawed, and  he lashes out on Missy who is 7,about 5 pounds, fixed, declawed, and timid. They have never gotten along. He's always establishing his dominence with her and he hurts her right in front of me. He knows its bad but can't help himself. It cost me a thousand dollers because he punctured her eye. He's also very demanding with me. He tells me when he wants a can,there's no procrastinating.(Very communicative) My third cat is 3 and she is a  big sweety. She acts like the middle man. Bruce never attacks her. Seems like the older he gets, the more he acts out. Especislly lateley.  I know he's not sick, we've been through that. He has digestion problems. No people food allowed and I've been mixing urinary tract food, easy digestion food, and hairball food together lately. Is that OK?  Anyway, I'd like to hear back on what you think. Thanx.

Hello AnneMarie, Bruce, Missy, and your third sweety!

Wow...what a forceful boy!  Have you considered giving Missy a room all her own that has all her necessities in it that even has a cat door in the door to the room that is magnetic (where she has the only collar that goes with it to unlock it)?  This might help quite a bit, as it will give her a place to go to get away if she feels intimidated or frightened.  I highly recommend giving it a try.  It would be good if it were a room that had quite a bit of your smell in it, and that you possibly even frequent, too.  

If you decide to give this a try, don't be surprised if she spends most of her time in there for the first week or two.  This is perfectly natural, and just her way of adjusting to things and getting so she feels comfortable with coming into other portions of the household again.

Let me know what you think, and please let me know if this isn't something you are able to do, so I can give you other ideas, ok?

Hugs to you and your furbabies!  :o)

Answer
Hello again!

Yes, it sounds like Feliway would definitely help.  It comes in either a spray (good for more concentration and smaller areas) and a plug-in (good for more constant emition and larger areas).  Both are good, really, just with the spray, you'll have to do it more often, but no big deal, really!  :o)

I would give that a shot and see how he reacts.  I'm not totally sure what the amount of time it takes for it to be effective, as I've never actually used it myself, but I've heard really great things about Feliway, enough so that I don't mind recommending it!  :o)

As far as a space for Missy, maybe even a closet would suffice.  Does she even try to hide anywhere?  If so, maybe you could try putting her necessities nearby that space in which she hides, so she doesn't have to go far and feels safer in general.  If that's not possible, either, the Feliway should have some effect, so you're on the right track.  :o)

Let me know how things go and keep me updated, ok?

Hugs to you all!
