I know it must seem as though I'm on continuous loop but I really believe that Clomicalm is the answer. As long as you get the dosage right (as little as possible) and give it to them before bed, it has a 24 hour residual effect and they won't be drowsy during the day and it won't affect their personalities. When I was in the middle of pee wars years ago, Boo would pee on the countertop and even once peed on the butter that I had left out. He never peed until I brought Specs in; Specs started the war. Then two others joined in and BAM! I was living in a giant litter box.

Like you, I was renting at the time and when I moved out, it cost me $900 to have the house professionally cleaned and to have the carpets steam cleaned. So do yourself a favor and give Clomicalm a try. Everyone, and I mean everyone, that comes into my home says that they can't believe that I have any cats at all. They can't smell anything. I've become so insane about the smell that I'd know if my cats were peeing again. It's been three years since I started my pee cats on Clomicalm and there have been no incidents. It'll save your sanity, your money and your home. Good luck, Melissa. I know how frustrating it can be and how you can have bad feelings about the cats that you so dearly love.
