ScoopFree Ultra Top Entry Self Cleaning Litter Box The PetSafe ScoopFree Ultra Top Entry Self Cleaning Litter Box is an innovative, automatic litter box that stays fresh and clean without the hassle. Instead of scooping every day, the litter box does all the work for you. Once your cat uses the litter box, lightly scented crystals absorb waste moisture and trap odor, while the automatic rake sweeps through the box and pushes the waste out of sight. Clean-up is as easy as placing the lid on the disposable tray and throwing it away. The top-entry hood has a large, grated surface to help eliminate litter tracking, and the built in health counter lets you know how many times your cat has used the box.
