A litter collection device for sifting animal waste using an improved sifting method is disclosed. The present invention provides a device comprising a device base and a chamber. The device base comprises a receptacle. The chamber located on the device base is filled with a litter material and receives the animal waste. The chamber is rotatable about an axis of rotation and further comprises a chamber opening and a partition. The chamber opening is operable as an ingress and an egress for the animal to deposit the animal waste, and is also operable as a waste opening for dumping the animal waste to the receptacle. The partition comprises screen sections and non-opening sections. The chamber is rotated such that the litter material passes through the screen sections and enters a trough, and the animal waste is kept out of the trough and dropped to the receptacle by the gravitational force.
