I am with this!! Our cat that we adopted in Dec of 2007 has decided to start peeing on the couch! I took him to the vet, he has a UTI !! Just spent $2000 last year for a urinary blockage! We got a leather sectional off craigslist! Every person in the family really likes it!! The previous owner had a monkey and I think the monkeys diaper leaked and got some urine on the couch and the cat smelled it and decided to mark his territory. We have tried cleaning it with vinegar, odoban and now I am ready to take it to the driveway and soak it down with cleaners and try to get it clean..this is a last ditch effort! If we can't get the smell out then I am afraid he will use it again!! If we do get rid of it...we have no couch and no $$$ to get a new one! Worried that when we do get a new couch that he will pee on it! He has never done this before, not sure if it is the animal smells or the leather.... ANYONE>>>CAN YOU HELP!!! PLEASE!!!!
