ScoopFree disposable litter tray replacements are the most hygienic way of having a clean cat litter tray for weeks and weeks at a time! These unique trays help you avoid touching and scooping cat waste from their litter tray. Simply replace the disposable tray every few weeks and your ScoopFree litter box is just like new. Replacement trays are pre-filled with premium super absorbant blue crystal litter for unbeatable odour control that's 5 times more effective than regular clay and clumping litters. Plastic lined trays prevent any leaks or spilling and the storage compartment will securely store solid waste until you are ready to replace it. Low-tracking and odour-reducing crystal litter keeps your home litter-free and smelling great.
