I've read about these products too and most of them seem to only mask the odor or give temporary relief from the things I've read. We even bought the expensive stuff from PetSmart called Urine B'Gone or something like that. While it worked in the bathroom, it didn't work in the places where the cat went repeatedly. We had even tried vinegar, baking soda, peroxide, and the Kilz primer spray cans. The smell didn't really budge. Cat urine is potent stuff. lol. I'm going to read up a little on "scabbing".
