I am kind of sad to hear i am not alone in this messy situation. I moved to Chicago from mass back in march, and for the first time ever in 9 years my 2 cats got along however upon returning to mass 6 most later a huge fight broke out. We had been in our new place for over a week when Levi ( 9 ) attacked Wendy (16) fur flying fight Levi even tried to get undernthe couch with Wendy to keep fighting. And this is hard for me also, about any ago I was living in a garden apartment and apparently something spooked Levi to the point he attacker Wendy and I . It was horrible !! He attached himself to the front of my leg with a paw on either side of my calf. Well a friend came and got him from under my bed and we put him in my spare room, about a day later I went to open the door and he charged right at it. I now get nervous when they fight. So the vet put him on kitty prozac , nothing for Wendy who I fear may be emotionally scared. All of this makes me wish I had stayed in Chicago, place was a miracle for them. I am also doing the baby gate thing andnits good, I don't free feed as suggested by Jackson galaxy so when ingot home they eat together but together time only lasts about 30 mins. Wendy gets pissy, starts growling which of course puts Levi on the defense ....its been a month now. I do have a split level 1 bdrm apartment so she was upstairs and he has been downstairs with me....I have a divider at the bottom of the stairs. Kitchen and living-room upstairs, bath and bedroom with small 3 ft hall downstairs. Tomorrow I am going to talk with a cat behavorist, we have been emailing and talking i have also been taking pictures and video. I have had many many cats in my life ( I am 56 ) NEVER NEVER EVER have I encountered such anything. I also am using the plug in and calming collars....hmmmm not sure what I think
