ABSTRACT:
A pet litter separator including a container and a sifter for separating the unsoiled litter from the animal excrement and soiled litter. The sifter includes a stationery first sifter element for retaining the animal excrement and soiled litter within the container and a vertically movable second sifter element for separating the unsoiled litter from the animal excrement and soiled litter. A sifter mounts the second sifter element for relative vertical movement with respect to the first sifter element. A plurality of first sifter openings are defined within the first sifter element. The second sifter element has a first vertical position closing the first sifter openings thereby retaining litter within the container and a second vertical position unobstructing the first sifter openings enabling the unsoiled litter to pass through the first sifter openings. An actuator is interconnected with the sifter for moving the second sifter element from the first vertical position to the second vertical position.
