PetSafe - Lucky Litter Cartridge - Purple

The ScoopFree disposable litter tray is the reason you can leave ScoopFree self-cleaning litter boxes alone for weeks at a time. With disposable trays, you don't have to see, touch or smell messy waste. Simply replace the disposable tray every few weeks and your ScoopFree litter box is just like new. Each tray is pre-filled with Premium Blue Crystals litter for unbeatable odour control that's 5 times more effective than regular clay and clumping litters. Low-tracking and odour-reducing crystal litter keeps your home litter-free and smelling great.
