Abstract: An animal litter composition includes bentonite clay, montmorillonite clay, and pieces of pine wood. In a particular embodiment, the animal litter composition has the following proportions of components by weight: bentonite clay, 40-70%; montmorillonite clay, 20-50%; and pine wood, 5-20%. In another embodiment, an animal litter composition has the following approximate proportions of components by weight: bentonite clay, 40-70%; montmorillonite clay, 20-50%; pine wood, 1-5%; and cedar wood, 2-8%. The clay mixture is believed to provide superior clumping characteristics over animal litters known in the art, and the pine wood, having a hollow capillary vessel structure, serves as a “biofilter,” effectively trapping moisture and odor.

Abstract: An absorbent material useful as an animal litter contains generally a wood product and clay particles. Specifically, the wood product in the preferred embodiment is wood particles from Western Red Cedar trees, which are nontoxic and nonaromatic. The clay particles are crystalline clay particles comprising calcium montmorillonite, sodium bentonite, attapulgite, and calcium bentonite. The material has the properties of being nontoxic, nonallergenic, nonaromatic, natural, and deodorant. The material further has the properties of enhancing clumping and coating solid material.
