There are four cat's in my household, but their (to my knowledge} is only one cat peeing all over my leather couches. When we First moved into this house the couches where previously pee'd on by the old owners sick cat. We where able to get it out then, but now it's treated like a litter-box my this cat. He wont stop. And we've scrubbed, and scrubbed. The obvious solution to this is to throw out the Couches, but we can't. Their now ours to depose of. We moved the couch but then the cat decided to pee where it was. I'm confused, and sick of my house smelling horrible. Please any advice would be greatly appreciated.
