摘要：
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.
