Litter box maintenance is a cinch with PetSafe ScoopFree Lavender Scented Non-Clumping Crystal Cat Litter! This disposable tray comes pre-filled with lavender-scented crystal litter. Crystal litter works by absorbing urine and drying solid waste, helping remove odors up to five times faster than clumping clay litter. The low-tracking, 99% dust-free formula and plastic pan liner help keep messes under control. Each tray can last up to 30 days in a single-cat home. Plus, 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! These replacement trays are compatible with PetSafe ScoopFree Complete self-cleaning cat litter boxes (sold separately).
