  • Patent number: 11918969
    Abstract: Animal litter comprising composite particles including powdered sodium bentonite and powdered activated carbon, agglomerated together into the composite particles, wherein the animal litter has a particle size distribution of 16/50 mesh (i.e., 300 ?m to 1180 ?m in size). The litter may include non-composite, granular clay particles (e.g., granular sodium bentonite) having the same particle size distribution (16/50 mesh). Such particle size characteristics significantly reduce dusting, without the need for a de-dusting agent, reduce clump depth and/or reduce clump width at the bottom of the clump (both acting to reduce risk of clumps sticking to the bottom of the litter box) and result in more efficient use of the litter in clumping (reduced clump weight) by increasing absorbency.

  • Patent number: 11684035
    Abstract: A clumpable animal litter comprises composite particles of filler materials, such as limestone and sand, and sodium bentonite. The filler materials have a lower bulk density as compared to a granular mixture of the same percentage of filler and sodium bentonite clay and contain up to eighty-five percent less clay.

  • Publication number: 20220400648
    Abstract: Animal litter comprising composite particles formed from renewable components where the composite particles include starch and dextrin agglomerated together. The dextrin may be included in an amount of from about 10% to about 50% by weight of the composite particles and the starch may be included in an amount of from about 50% to about 90% by weight of the composite particles. The composite particles may optionally include powdered activated carbon. The litter may advantageously be free or substantially free of non-renewable mineral components, and may exhibit a clump retention of at least about 90% and/or a clump strength of at least 1,000 gf.

  • Patent number: 10212916
    Abstract: Animal litter having up to a sixty percent reduction in bulk density can be produced by combining flat-shaped cellulosic materials and sodium bentonite clay. Not only is the resulting litter lighter, but it also maintains a high clump strength as compared to clay-based animal litters that contain greater than ninety percent by weight sodium bentonite clay.
