The PetSafe ScoopFree Stainless Steel Reusable Tray is the ONLY stainless-steel option designed to work seamlessly with all ScoopFree Crystal litter box systems, including the new generation of ScoopFree Pro and ScoopFree Plus cat litter boxes. Made from powder-coated, rust-resistant stainless steel, this cat tray is built for long-term everyday use. Its nonabsorbent, stain-resistant surface stays cleaner longer, while the rounded edges help reduce mess and residue. An included waste shield helps contain odors and the tray comes with a 4.3 lb bag of pre-portioned, PetSafe Premium Blue Crystal Litter for advanced odor control.
