| A litter and litter making method producing cat litter from a carbohydrate starch-containing cereal grain, e.g., corn, based admixture extruded from a single screw or twin screw extruder forming pellets having a clumping agent formed during extrusion composed at least in part of carbohydrate polymer binder. Each pellet is extruded under conditions that cause formation of carbohydrate polymer binder clumping agent at least some of which is water soluble. One preferred method of extruding cat litter causes starch dextrinization to occur such that at least some of the carbohydrate polymer binder clumping agent in each pellet is formed of dextrin. Each pellet can be coated such as with a smectite that preferably is bentonite. During use, pellet extrusion formed clumping agent in a pellet wetted with urine dissolves and flows in between and along adjacent pellets causing them to clump together without the presence of any clumping agent additive. | ||||||

Thus, the powdered material ensures high productivity. The powdered material is a powdered polyurethane urea resin composition which comprises (D) a polyurethane urea resin that has a total content of bimolecular condensate of acetone, bimolecular condensate of methyl ethyl ketone, and bimolecular condensate of methyl isobutyl ketone of 1,000 ppm or less and (N) an additive, wherein the polyurethane urea resin (D) takes the form of thermoplastic polyurethane urea resin particles (P) that have a volume-mean particle diameter of 20 to 500 μm and that have protrusions and recesses on the surfaces. The powdered polyurethane urea resin composition is manufactured by a manufacturing process which includes a step of mixing (A) an isocyanato-terminated urethane prepolymer with (B) an alicyclic diamine and/or an aliphatic diamine in an aqueous medium by stirring to form the resin particles (P). | ||||||
