Abstract
An animal litter including an extruded smectite clay that forms stronger clumps, when wetted with animal urine, due to the extrusion process. In a preferred embodiment, the extruded smectite clay is mixed, before or after extrusion, with a small percentage, preferably at least about 0.025% to less than 0.1%, based on the dry weight of the smectite clay, of a water-soluble adhesive that forms improved, stronger, more cohesive clumps that can be essentially completely removed from a litter box leaving the remaining litter box contents odor-free.
