The smell of cat urine is very hard to get rid of. You may try other methods, but success will come when you use Urine Off. It is a bio-enzymatic formula that gets to the root of the problem. Cats tend to urinate where they have in the past. One of the best ways to stop it will be getting rid of the urine smell that drives them back to the same spot. The enzymes in Urine Off get rid of the salt crystals that stay in the carpet, even after cleaning. If the salt crystals are not removed, the smell will come back just as strong.
Urine Off is a safe cat pee remover.
