Extruded Self-Clumping Cat Litter

摘要

Litter formed of extruded pellets containing water soluble binder sufficient to self-clump when wetted producing pellet clumps having a clump retention rate of at least 90% and which shrink after clump formation during drying producing a clump pulls away from any contacting solid surface minimizing adhesion therebetween. Such clumps preferably also have a crush strength of at least 15 PSI when dry. Pellets preferably contain water-soluble binder formed of starch physically modified during extrusion that solubilizes when wetted to facilitate clumping while opening the interior of the pellet improving absorption capacity. A preferred litter is formed of a mixture of extruded pellets of different sizes producing litter composed of extruded pellets falling within a plurality of different size ranges with the smaller sized pellets being fines that cause horizontally extending clumps to form on top of the litter.

主权项

1. An extruded cat litter formed of a plurality of pellets extruded from a starch containing material having sufficient water soluble adhesive formed from starches modified during extrusion to self-clump together when wetted forming clumps comprised of at least a plurality of pairs of the extruded pellets bonded together by the water soluble adhesive.
