US Patent 11457604 Animal waste handling device and method

A device is capable of filtering animal waste with an improved sifting method. The device includes a support bracket, a chamber attached to the support bracket, and a screen filter located within the chamber when the animal deposits the waste. The chamber has an opening adapted to accommodate the animal to deposit the waste inside the chamber. The chamber is rotatable between a first position and a second position. The screen filter is movable between a third position and a fourth position. The rotation of the chamber and the movement of the screen filter can be independently managed, thus achieving a better result of animal waste handling.
