Abstract

The invention provides a waterproof litter receptacle for use in disposal of animal waste products. The litter receptacle contains a mixture of non-smectitic, hydrophilic shale aggregate. The mixture of non-smectitic hydrophilic shale has a fraction of coarse material with a size less than about 5 mesh (4000 microns). The mixture has the property of agglomerating into a clump upon contact with urine. The agglomerated clump of shale and urine is removable with a perforated scoop. A substantially dust-free distribution of shale of greater than 50 mesh (300 microns) is capable of clumping without additives. Optionally, the shale may contain up to 10 weight percent clumping agent selected from the group of water absorbent polymers, corn starch, gelatin, gluten and dried plants of the Plantago family. In addition 5 to 25 wt % ammonia absorbing zeolite may be added for odor control.
