Uric acid crystals are the source of bad odors and are the most difficult to eliminate. The live bacteria in our unique* formula produce enzymes that bind to the uric acid crystals left behind by urine, breaking them down and making them digestible by the bacteria.

When the bacteria are moist, they continue to produce an increasing population of enzymes that remain active on the stain until the source of the problem, namely uric acid, is completely eliminated. The bio-enzymatic bacteria activate and produce enzymes that remove stains and the source of unpleasant odors.

Urine Off® Cat Surface is the No. #1 product recommended by veterinarians for removing urine odors and stains. It eliminates all urine components—including dried uric acid crystals—which are the main cause of repeated marking.

Urine Off Cat & Kitten has a fabric softener scent.
