Urine Off Cat & Kitten Formula is a veterinarian-recommended product for feline urine odor and stain removal. Urine Off Cat & Kitten Formula uses bio-enzymatic technology and a high bacteria concentration to specifically target cat and kitten urine, permanently removing stains and odors from virtually any surface. The combination of micro-organisms and their enzymes in our non-pathogenic bacteria work together to breakdown the uric acid that produces urine?s pungent aroma and the urea that sticks to the surface, effectively removing all components of the urine, when used as directed. Urine Off is a USDA Certified Biobased Product and holds the Carpet and Rug Institute?s Seal of Approval. Urine Off is safe to use around pets and people.
