miraculous way to control litter odor! Nature's Miracle uses natural enzymes that react with your cat's urine. Every time your cat goes to the bathroom, more enzymes react, for continuous odor control!. Also great for use in small animal pens, snake or other reptile pens, rabbits, and pot belly pigs. Instructions: Starting with a fresh, clean litter box, sprinkle Nature's Miracle on top of the litter, about 2 tablespoons per pound of litter. No need to mix, your cat's natural digging action will mix the litter. Continue to remove feces as usual.
