Abstract: The device selectively separates and removes larger sized objects from a mixture of larger and smaller sized objects, such as soiled litter and animal waste from surrounding clean litter. The device has a rotating chamber which contains the mixture of larger and smaller sized objects with an opening for entry into and out of the chamber, and for expulsion of separated larger sized objects out of the chamber. A separating element, which is disposed longitudinally on the interior of the chamber, is passed through the mixture of larger and smaller sized objects to separate the larger sized objects from the smaller sized objects during the rotation of the chamber. As the chamber rotates, the separated larger sized objects, such as soiled litter and animal waste, are transferred from the separating element to a pivotable ramp in the interior of the chamber.
