  • Patent number: 5577462
    Abstract: An animal litter container for separating reusable animal litter from clumps includes a disposal unit having a screen with a handle extending therefrom, and two shells which may be engaged to form an enclosure from which substantially no litter can escape. When the litter is to be cleaned, the disposal unit is placed with its handle extending outside the unused shell and its screen resting within. The shells are inverted so that the litter and waste falls from the used shell onto the screen and into the unused shell, and the used shell is removed. The handle is then used to lift the screen from the unused shell, sifting the waste clumps from the litter.
