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. The weight of separated larger sized objects causes the ramp to pivot to an inclined position which allows the separated larger sized objects to slide down the ramp and out of the chamber into an appropriate receptacle. A system of seals are provided as part of the receptacle to seal the separated larger sized objects inside the receptacle to allow multiple separations of the mixture of larger and smaller sized objects before disposal of the separated larger sized objects is required.
