ABSTRACT:
An improved automated litter box system which provides increased storage capacity of a waste receptacle which receives animal waste and clumped litter. The increased capacity of the waste receptacle is achieved by elevating the automated litter box system with an elevating apparatus so that a replacement waste receptacle of larger volume can replace the waste receptacle of the litter box system. The invention provides improved automated litter box systems which incorporate such a large volume waste receptacle as a component thereof. The elevating apparatus includes an elevated platform on which the lifter box system is placed. A ramp is provided to provide animal access to the system placed on the elevated platform.
