Revolutionary cat litter box that is truly hands free and scoop free. The crystal litter that is used quickly masks odors and crystallizes waste to get the box smell free. Once the cat leaves the box the sensor awaits a short time and scoops the waste into the side panel. The second generation box fixes the struggles of the prior with no clumping nor bunching of the waste on the grates. This product is wonderful for those who hate to change the litter but require a odor free environment.
