Does anyone have any recommendations regarding on how to teach a cat that the litter box is the only place to take a leak, not the living room furniture?? My wife and I have 2 yr old cat who in the last 6 months has started peeing on our the couch and chair in our living room. We clean out the litter box daily and change the litter weekly and have used almost everything on the market to clean the furniture and remove the cat pee smell but the cat continues to relieve herself on the furniture. We are really attached to her and getting rid of her is our last option. Thanks in advance for any ideas.
