Abstract
A process of creating cat litter which comprises forming a mixture of opal clay with one or more of the following three constituents: sodium bentonite calcium lignosulfonate binder The material is then mixed. The resulting mixed material is then pelletized in a disc pelletizer to form small round pellets. The resulting pellets are dried and then screened to produce a product having a fairly uniform pellet size averaging between a -6 and +30 mesh while removing substantially all dust and small particles. The resulting product forms a cat litter which has a clay base, yet is substantially dust-free and flushable. The litter will clump upon the absorption of liquids, such as cat urine and feces, allowing the trapped liquids and solids to be removed as a clumped ball for flushing or disposal.
