  • Animal litter and related processes
    Patent number: 4685420
    Abstract: This invention relates to an animal litter comprising a porous, inert solid substrate and a dry particulate polymer. When animal urine contacts the animal litter there are produced gelled agglomerates containing the animal urine, polymer and solid substrate. The gelled agglomerates have sufficient mechanical integrity to be conveyed as discrete entities thereby permitting animal urine to be physically removed from a litter box containing the animal litter of the present invention.
