PetSafe ScoopFree Crystal Pro Self-Cleaning Cat Litter Box, Covered, White
Digital Visit Counter, LED Tray Indicator, Health-Tracking, No Scooping For Up To 30 Days, Covered Automatic Litter Box
My cats refused to get inside it even once. I have a pack of the litter crystal trays that go with it. $125 for only the litter box and $50 for the new 3-tray pack (new is $75).
