BioSand is a high-clumping sand for cats that does not cause allergies

BioSand is a fine, highly clumping Italian cat litter composed of the natural, refined mineral bentonite. It collects waste so well that liquids cannot reach the bottom of the box. It collects waste in small balls with the smell of baby powder. Made from 100% pure natural bentonite. It makes it easy to monitor your cat's health from the color of urine.
