The instant invention is directed towards a clumping animal litter comprising a combination of a high molecular weight polymer, a gum, and cellulosic components, and methods of preparation thereof. The invention particularly relates to a clumping animal litter that comprises a homogenous mixture of anionic polyacylamide, a guar gum, grist and optionally cellulosic fines in combination with one or more sources of cellulosic material, thereby providing a litter with enhanced absorption, clumping size and hardness.

What is claimed is: 1. A clumping animal litter composition for forming substantially solid clumps upon contact with an aqueous solution comprising in combination: an absorbent polymer in amounts between about 0.1% to about 1.0% by weight based on the total weight of the mixture; a gum in amounts between about 5.0% to about 20.0% by weight based on the total weight of the mixture; and a grist; wherein said absorbent polymer, said gum and said grist are supplied in amounts sufficient to form a homogenous mixture, whereupon hydration with said aqueous solution forms nearly instantaneous clumps. 2. The clumping animal litter composition according to claim 1, wherein said absorbent polymer contains an anionic polyacrylamide comprising an acrylamide and an anionically charged co-monomer, wherein said anionically charged co-monomer includes at least one salt of acrylic acid. 3. The clumping animal litter composition according to claim 1, wherein said absorbent polymer contains an anionic polyacrylamide with an average molecular weight of about 5,000,000 to about 30,000,000. 4. The clumping animal litter composition according to claim 3, wherein said anionic polyacrylamide has an average molecular weight of about 10,000,000. 5. The clumping animal litter composition according to any one of claim 1, claim 2, claim 3 or claim 4, wherein said anionic polyacrylamide is provided in amounts of about 0.3% by weight based on the total weight of said mixture. 6. The clumping animal litter composition according to claim 1, wherein said grist is obtained from at least one source of softwood. 7. The clumping animal litter composition according to claim 6, wherein said softwood is at least one selected from the group consisting of yellow pine, lodge pole pine, cedar and combinations thereof. 8. The clumping animal litter composition according to claim 1, wherein said gum is selected from the group consisting of hydroxypropyl guar, carboxymethyl guar, carboxymethyl hydroxypropyl guar, xanthan gum, and locust bean gum, including derivatives and combinations thereof. 9. The clumping animal litter composition according to any one of claim 1, or claim 8 wherein said gum is provided at about 10.0% by weight based on the total weight of said mixture. 10. The clumping animal litter composition according to claim 1 wherein said mixture further comprises an additive selected from the group consisting of a biocide, antimicrobial, deodorants, disinfectants, colorants, fragrance, oxidizer and combinations thereof.
