No scooping, cleaning or refilling your cat’s litter box for weeks. Crystal litter removes the smell by absorbing urine and dehydrating solid waste. Low-tracking crystals are 99% dust free and don’t stick to your cat’s paws; a hooded cover helps keep kitty litter inside the box. Disposable trays have a plastic lining to help protect against leaking and keep your floors clean. Simply remove the tray and throw it away; each tray includes a lid for quick disposal. The health counter and motion sensors keep track of how many times your furry feline uses the box.
