Our Real Citrus product is intended to be used as an air freshener, and our label instructs the user to "Spray a light mist high in the air." We do not recommend using this product to clean a litter box or spray directly onto cat litter. Our Real Citrus label does state that the product "Eliminates odors from: smoke, pets, cooking, garbage, litter boxes, mold, mildew, and other foul odors." To avoid further confusion regarding this matter, the term "litter boxes" will be removed from our Real Citrus cans in future production runs.
