Have the same problem in our home right now, only I can not catch which cat is urinating on our
couch. Our
couch is leather and I put throws down
on the seats, this is where someone is urinating. They are also urinating on throw rugs, last night on our bed....wherever they choose. I have laminate floors, so needless to say they are washed daily, rugs and throws are always on the clothesline and I am still waiting to find out who is doing it. We brought in 2 male kittens 4 months ago.
