PetSafe self-cleaning litter boxes

PetSafe's ScoopFree line spans three different ideas: rake-over-crystal-tray boxes that need a disposable tray, a rake box for clumping litter, and two newer connected designs, the SmartSpin drum and the OpenSky open-top. Its user guides are unusually explicit about kittens.
