PetSafe ScoopFree Litter Tray Refill With 'Free' Crystals White 22" x 14.5" x 2.5"

Free trays don't have a lid so they can nest, making them easier to stack and store in small spaces. Each tray includes a garbage bag for easy disposal. The crystal litter provides superior odor control and the tray includes a covered waste compartment that locks in odors, so you can leave the tray alone for weeks at a time. It is completely disposable for hands-off convenience, so you don't have to touch or smell messy waste. After a few weeks, simply toss the tray in the provided disposal bag and replace with a new one. These trays work with ScoopFree self-cleaning litter boxes and ScoopFree Slide. Covered waste compartment locks in odors and leaves litter smelling clean and fresh. Plastic lining creates a powerful barrier to help protect against leakage. Crystal litter doesn't clog rake or clump to the bottom of the tray. Uses 5 to 10 times less than clay and clumping litter, so there's less to buy and bring home. The low tracking litter is 99% dust free. Safe for all cats. We recom
