Each ScoopFree® Disposable Crystal Litter Tray is pre-filled with premium blue crystal cat litter, so all you have to do is load the tray in the litter box with no scooping, cleaning or refilling for weeks! Crystal litter absorbs urine and dries solid waste to quickly remove odors 5 times faster than clumping clay litter. Low-tracking crystals don’t stick to your cat’s feet and are 99% dust-free—designed for all the days you don’t want to sweep the floor (again). And the plastic tray lining creates a powerful extra barrier to protect your floors against leaks. When it’s time to clean up, just remove the disposable litter tray and throw it away. It doesn’t get much easier than that! Your pet deserves the best. Trust PetSafe® to help keep your pet healthy, safe and happy.
