Patent attributes
A self-cleaning litter box. The self-cleaning litter box includes a basin designed to rotate about an axis, having a hollow center with an interior volume designed to hold litter. An aperture is disposed in the basin designed to provide access to the interior volume. A filter screen disposed within the interior volume and extending across the basin is designed to sift excrement from the litter. The basin is disposed within a base that supports the basin. A waste container is positioned within the base. The waste container includes an opening in communication with the basin such that the aperture of the basin fits flush against the opening of the waste container when the basin is rotated for sifting excrement. In one embodiment, the self-cleaning litter box incorporates a motion sensor, a weight sensor and a wireless transceiver.
