Strike scooping the litter box off your to-do list. With the ScoopFree Covered Self-Cleaning Litter Box, there's no scooping, cleaning or refilling your cat's litter box for weeks. It uses crystal litter that provides 5 times better odor control than traditional clumping litter by absorbing urine and dehydrating solid waste. This low-tracking litter also helps keep your floors clean because it is 99% dust free and doesn't stick to your cat's paws. Safety sensors ensure that the scooping cycle only occurs when your cat is out of box.
