Urine Off, the #1 Veterinarian recommended for urine odor and stain removal, breaks down dried uric acid crystals – the primary source of odors caused by small animal urine. Not a perfume or cover-up, it actually eliminates urine. Urine Off is ideal for cleaning cages and areas where small animals are kept. Can be used on all surfaces including upholstery, carpet, hardwood, tile, grout, vinyl flooring, and cage surfaces.
