That's such a hard thing to control and I really feel for you and Alexa. Is the name of the medication Amitriptylin?

I've recently read a lot on cat peeing/spraying and Prozac seems to be the number one choice from recent studies. The studies found that the medication could easily be discontinued successfully without any side effects or for the cat to return to that behavior. Just additional info.....my head is full right now.

Either way, I really hope this is a solution for you guys. It's so disheartening to deal with this. Best of luck!
