There is a product at the pet store, but it tends to be expensive. I would rather have a bare floor, nothing there at all, than to live with the smell. I did have to take up carpet in my bathroom in Mo. I was lucky in my case the bath was small, I re-did the tile myself which is actually easy to do. After this particular cat decided to pee in a pumpkin on the dining room table, I had to give up with this animal however. It didn't turn out well as there was no stopping the behavior. I can't take the amonia, and I would take up the carpet as the liquid penetrates to the floor. A washable throw rug could be used instead. I do with you all the best with your kitties. Wish there were an easy way to stop it. Ask your Vet too for tips. ginnie
