We love our cats, but when they stop using the litter box & have messes it's time for serious action. No product works faster to get cats back to using the litter box and remove messes from urine, vomit, hair balls, feces, marking scents, and cat spray. This is the only product that can remove the invisible sticky mucous & pheromones that remain after urination or spraying, permanently removes new or old scent & urine odors left behind even after cleanup with other stain and odor products.
