A recently granted patent (Publication Number: US11918969B2) discloses an innovative animal litter formulation designed to enhance absorbency and reduce dusting. The litter comprises composite particles consisting of powdered sodium bentonite and powdered activated carbon agglomerated together, with a particle size ranging from about 300 µm to 1180 µm. This unique composition results in an absorbency level at least 40% higher than traditional litter products within the 425 µm to 2360 µm particle size range.

Furthermore, the patent includes a variation of the animal litter, which combines granular clay material with the composite particles. The composite particles, comprising powdered sodium bentonite and powdered activated carbon, are present in the blend at 20 to 50% by weight, while the granular clay material, such as granular sodium bentonite, makes up the remaining 50 to 80%. This blend also demonstrates an absorbency level significantly surpassing conventional litter products, showcasing the innovative approach to improving litter performance and efficiency in managing pet waste.
