I can feel your frustration and exhaustion w/every word, Jen. The house that I rented was the same way and when I bought this house, I made up my mind that either the pee cats stop or I would find homes for them. My RB Peeka was one of the worst offenders and I think it was because she hated Pigeon so much. Poor Pidge is the sweetest cat in the world and spent the majority of her time under my bed because Peeka stalked her constantly. Since that time, however, my vet introduced Clomicalm and it's been a life saver. Literally. The only suggestions I have are to give Clomicalm a whirl and shut off any parts of the house where you don't want your cats to go. I don't even allow mine to sleep w/me any more for two reasons: first and foremost, I need my sleep, good REM sleep. And I wasn't getting it because I was accommodating my cats. And second, they became territorial and then considered my bed/room their territory and started spraying there, too. The night that Peeka actually peed on ME, in my hair, was the last straw! I tried putting plastic on several things, too, to no avail, because my vet told me that cats hate plastic. Lovely. If you will just give Clomicalm a try and hopefully, it will kick in right away, you might have peace and not "pees" in your household. It's your house and if you consider your cats to be family, ok, but would you let your human family pee and poop wherever they want to? Of course not. And that's the question I had to ask myself and it was the turning point for me. Good luck, girl. I hope you get some relief soon.
