Abstract
Compacting expanded perlite fines in the presence of a small amount of binder (starch and/or clay) and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a small amount of clumping agent (e.g., guar gum) to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.
Claims10
A pet litter comprising dried particles of compacted material comprising 50 wt. % to 85 wt. % expanded perlite, wherein the dried particles further comprise a binder comprising starch, wherein the dried particles do not contain a clumping agent and wherein the dried particles have a density of about 25.0 lb/ft3 to about 45 lb/ft3.
A pet litter comprising dried particles of compacted material consisting essentially of expanded perlite and starch, wherein the dried particles have a density of about 25.0 lb/ft3 to about 45 lb/ft3.
