My wife and I are at our wits end with two of our cats and want to see what advice people have for us. Here's the problem:
Larry, a male, stalks and attacks Curly Sue, a female. In the past, we have witnessed fights between them starting and were able to break them up: usually they start with Larry "looking at Curly Sue funny" - almost like he is stalking her - and Curly Sue hissing and growling at Larry. This causes Larry to get more agitated, his tail poofs, and he goes into full-on stalking mode. If not stopped, he starts attacking Curly Sue.
Obviously we try and stop this whenever we can, but sometimes the cats are in another part of the house or we are asleep and we don't hear the commotion until it's too late.
If we are not around to stop Larry's stalking and Larry attacks Curly Sue, Curly Sue lets out a blood-curdling series of screams. During the commotion, Curly Sue urinates all over herself, Larry, and whatever else is nearby.
Obviously I feel terrible for Curly Sue - she is so scared that it's causing her to urinate herself. But this is also causing a lot of stress on my wife and I, and a lot of property/furniture damage from the cat urine. The other day this happened in the middle of the night under the bed and ruined our box spring. Dealing with Curly Sue soiling herself and Larry, the box spring, and moving and cleaning under the bed was not fun.
We have gone through a separation and re-introduction process several times in the past, but inevitably Larry's violence toward Curly Sue always rekindles. This happened several years ago in our old home, and we ended up keeping Curly Sue locked up with food, water, and a litterbox in our spare bedroom when we were not home. Although I didn't like making our spare bedroom a "cat room", it solved the problem and Larry never attacked Curly Sue while we were home. We had not had any issues in our new home until recently. In contrast with the situation in our old home, Larry now attacks Curly Sue while we are home and awake! It's gotten so bad that I am not going to let them intermingle at all; one cat is going to stay in the spare bedroom until we can figure something out.
To clarify, neither cat has a problem using the litterbox. Curly Sue will only let off a "urine grenade" when Larry attacks her like this.
I cannot think of any changes in our home that would have triggered this behavior. Also, we have tried Feliway products in our home, but they have not affected this behavior.
We are thinking of asking our vet to put one or both of them on a psychotropic drug to calm them down. Short of putting one of them up for adoption, I do not know what else to do.
Both cats are normally very sweet and gentle. This behavior is so strange.
