Abstract: Litter compositions comprising a blend of compacted granules comprising expanded perlite fines and coated granules, each coated granule comprising a non-agglomerated particle and a coating comprising a clumping agent on an outer surface of the particle are disclosed herein.

Abstract: Compacting expanded perlite fines in the presence of a 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 clumping agent to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.

Abstract: Animal litter compositions having relatively low densities are described herein. Methods of manufacturing such litter compositions are also described.

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.

Abstract: A method of making a non-clay based clumping pet litter can include blending a natural material; compressing the blended natural material into pellets; grinding the pellets into granules; screening the granules to obtain a predetermined size range; and applying functional additives to the sized granules. The functional additives can include a clumping agent, mineral oil, and a surfactant. The natural material can be one or more of recycled paper, corrugate, and sawdust. The functional additives can further include a fragrance oil. The clumping agent can be guar gum, and the surfactant can be a polysorbate. In another aspect, a non-clay based clumping pet litter contains granules of compacted natural material enrobed by a coating containing a clumping agent, mineral oil that adheres the clumping agent to the granules, and a surfactant.

Abstract: The invention provides extruded animal litters and methods of making and using such litters. The animal litters comprise an extruded mixture of from about 10 to about 90% of one or more clays and from about 90 to about 10% of one or more starches. The use of starches to produce the extruded litters result in litters that are less dense than conventional clay-based animal litters and are therefore easier to transport and use.

Abstract: Litter boxes are provided that have a tear-away flap on the top and/or the front of the box. The tear-away flap can be pulled outward from the box to form a mat that can provide an entry to the box. Positioning the tear-away flap as a mat can expose a corrugate fluting structure on the tear-away flap. This structure can act as an anti-tracking trap as the cat leaves the box with litter on the paws. An overhang on one or more sides of the box (preferably three sides) can prevent litter from “splashing” out of the box onto the floor. After the pet owner is finished using the litter box, the pet owner can fold the tear-away flap back onto the top of the box to reseal the box to keep the litter in the box for disposal.

Abstract: The invention provides animal litters that have an increased absorption rate and methods of making and using such litters. The animal litters comprise one or more animal litter particles that have been produced by fragmenting extruded animal litter particles that have a film on the surface of the particle that adversely affects the absorption rate. The fragmenting exposes the interior of the extruded animal litter particles, which does not have this film, to the external environment and increases the absorption rate.

Abstract: The invention provides odor control systems having customizable aroma and malodor control compounds. In a general aspect, the odor control system includes a litter box and a programmable dissemination device attachable to the litter box. The programmable dissemination device is adaptable to receive at least one odor control cartridge and disseminate the contents of the cartridge. The odor control cartridge is a fragrance cartridge or a malodor counteractant cartridge insertable into the programmable dissemination device. Alternatively, the odor control cartridge can include a fragrance and a malodor counteractant in the same cartridge.
