If you come up with a good way to clean couches, would you let me know? I've tried about 6 different products on our couch that Rookie peed on . . . and now it just smells like those products, combined with a ilttle pee. I've kind of given up.
I don't know if your cat would fall for this, but Rookie stopped going up there when we took the couch pillows and put them on the edge, pointing diagonally out. She saw those points sticking out as a barrier, I think. She's also a fraidy-cat, so your cat might not be deterred by that.
