Abstract
An animal litter such as a clay material is treated to reduce the bulk density thereof by contacting the clay material with an aqueous electrolyte solution and then heating at an elevated temperature. Substantial reductions in bulk density have been achieved without reducing the absorption capacity of the clay granule.
