Is a cat reintroduction possible?

Hello, we currently have a household with three cats, with our newest, Billy, having arrived around August 2010. We have noticed aggressive, mean behaviors coming from or eldest (and alpha) cat, Pumkin. After so long of thinking she just wasn't a "cat person", we now believe we may have caused it by introducing them improperly. Billy seemed just fine and plenty confident right away as soon as he arrived so we let him free roam within hours of his arrival. Could this be what has caused Pumkin's animosity towards Billy? We have tried many methods of both positive and negative reinforcement, but nothing seems to work. Is it too late to retry an introduction? At this point it seems a little silly since they've been around each other so long. Thanks!

We must assume that all your cats are spayed or neutered. If not, this is your first step. Yes, the introduction was not done correctly, No matter how well things went within a few hours of bringing Billy home, it probably would have been better to keep Billy separate from the others for at least a week or so. You don't say what your "negative and positive" reinforcements were, but this might have added more confusion to the mix. Pumkin may have alpha issues and Billy may not be accepting of her status within the cat hierarchy in your home. If you don't want to rehome Billy, you may just have to accept that Pumkin and Billy just don't get along. This does happen in multi-cat households. You can try reintroduction, but I would chat with your vet first, who hopefully knows your cats, to find out the best way to go about this. They can offer advice on how to reintroduce Billy and Pumkin, but as you said, after this long, it might not work.
