US Patent 9185879 Litter box assembly

A litter box assembly for house pets is disclosed, which includes a container rotatably mounted to a stand, allowing the litter box to rotate from its normal position to a cleaning position and/or a resetting position. The litter box assembly includes contact portions that contact a portion of the stand or the floor in the cleaning position and the resetting position. When the contact portions contact the stand or the floor, the vibration of the litter box container caused by the contact facilitates the movement and dislodging of litter and waste. This contact can be repeated to facilitate the cleaning of the container.
