ScoopFree® is the self-cleaning litter box you can leave alone for weeks at a time. The special crystal litter, packed in a convenient disposable litter tray, is 5 times more effective at reducing odor than clay or clumping litters. Simply plug in the box and watch it work. The automatic rake system sweeps waste into the covered compartment minutes after your cat uses the litter box. The health counter lets you track how many times your cat has used the litter box to quickly identify possible health problems.
