Abstract
Abstract An improved pet relief station for the receiving of pet excrement, the relief station comprising a screen pan having a screen portion, and a pair of receiving pans that are alternatively stackable one in the other. The screen pan is placed in one of the receiving pans, and this pan is in turn stacked in the other receiving pan. Pet litter is disposed in the screen pan to cover the screen portion thereof. Once pet solids have been deposited on the pet litter, the solids are removed by lifting the screen pan, sifting the pet litter which separates the pet solids onto the screen portion, and disposing of the solids. Immediate reassembly of the relief station is afforded by separating the receiving pans, positioning the screen pan in the empty receiving pan, and then pouring the litter over the screen portion of the screen pan. The receiving pans are then restacked.
