This stuff really does work. I have a cat that is strangely attracted to peeing on my new sofa and love seat (there must be something about the fabric). I've now resorted to aluminum foil and pet spray to keep her off, but in the meantime the smell was nauseating. I tried everything recommended by everyone, and then you just smell both. I tried My Pet Peed and it worked like a miracle. Odor completely gone. I'm a happy camper.
