Abstract
Abstract Fly ash, bottom ash and/or boiler slag are used as animal litters and particularly as cat litters. These materials exhibit remarkable absorbent and deodorizing capabilities and their low cost makes them a commercially more attractive substitute for Fuller's earth and other currently available cat litter compositions. These materials are also effective when used in admixture with Fuller's earth or other known cat litters.
