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.
A waterproof litter receptacle for use in disposal of animal waste products, said litter receptacle containing a mixture of hydrophilic shale aggregate, said mixture of hydrophilic shale having a fraction of coarse material with a size less than at least about 5 mesh (4000 microns), said mixture having the property of agglomerating into a clump upon contact with urine, and the clump of agglomerated shale and urine being capable of physical removal with a perforated scoop.
A waterproof litter receptacle for use in disposal of animal waste products, said litter receptacle containing a mixture of hydrophilic shale aggregate, said mixture of hydrophilic shale having a fraction of coarse material with a size consisting essentially of less than at least about 5 mesh (4000 microns) and greater than 50 mesh (300 microns), said mixture having the property of agglomerating into a clump upon contact with urine, and the clump of agglomerated shale and urine being capable of physical removal with a perforated scoop.
A method of controlling disposal of animal waste comprising the step of:
An animal litter comprising hydrophilic raw shale having a particle size less than 5 mesh (4000 .mu.m) and 0.025 to 10 weight percent dried plantago plant, said mixture of raw shale and plantago plant being capable of agglomerating with urine to form removable clumps.
