Scoopfree Litter Box 2nd Generation Cross cleaning the litter box off your list of things to do. You won't have to scoop, clean, or refill your cat's litter box for weeks with the ScoopFree Self-Cleaning Litter Box. It makes use of crystal litter, which has a 5 times greater ability to suppress odours than conventional clumping litter. Crystal litter dehydrates solid waste while absorbing urine. Because it is 99% dust-free and doesn't stick to your cat's paws, this low-tracking litter also helps keep your floors clean. Safety sensors make sure that the scooping cycle only starts when your cat is out of the box; the cycle begins 20 minutes after your cat has left the litter tray. It uses disposable trays that have a plastic lining to help protect against leaking, and each tray comes with a lid for quick and easy disposal. Just remove the tray and throw it away. There’s even a health counter that tracks how many times your furry feline uses their cat toilet, which is a convenient way to detect early signs of a health issue. Trust PetSafe to keep your pet healthy, safe and happy.
