ScoopFreeT is the world's first automatic, self-cleaning litter box you can leave alone for up to 30 days! ScoopFree features a unique 30-Day Throwaway TrayT which you replace as little as once a month without any scooping, refilling or cleaning. 20 minutes after your cat leaves the litter box, ScoopFree will automatically rake the waste into the tray's covered trap so you can enjoy hands-off convenience for weeks at a time. How? Each Throwaway Tray comes already filled with Fresh Stepr Crystal litter, which provides unbeatable odor control. The Fresh Step crystals lock away the odors, absorb the liquids and dehydrate the solids to keep everything smelling clean and fresh. As little as once every 30 days per cat, discard the entire Throwaway Tray without having to see or touch messy waste. Then insert a new tray filled with fresh litter and ScoopFree will keep everything smelling clean for up to another month.Safe for You and Your CatRoomy and comfyDesigned with gentle curvesNo sharp points on rake, which has rounded loops for extra safetyRake stops if it encounters an obstructionCountdown timer resets if cat re-enters the boxTested and ReliableResists clogging and jammingPowerful and durable motorShhhh.it's really quiet!Designed in the USAPatents Pending
