Abstract: The present invention pertains to a natural product litter composition as well as methods of preparing and using a natural product litter as a sorbent for liquids. The sorbent contains 1 to 10% by weight Aspen particles and 90 to 99% by weight ground grain byproducts including red dog wheat and wheat middlings. The sorbency of a ground grain litter can be improved by pelletization and crumbling.

Abstract: The present invention pertains to a natural product litter composition as well as methods of preparing and using a natural product litter as a sorbent for liquids. The sorbent contains 1% to 50% by weight wood particles and 50% to 99% by weight ground grain. The sorbency of a ground grain litter can be improved by pelletization and crumbling. Addition of up to 50% of wood particles to a ground grain litter further enhances the sorbency while maintaining suitable swelling and clumping characteristics.

Abstract: The present invention provides an improved method for sorbing aqueous fluids through the use of a biodegradable, clumping, low odor, low attrition, low swelling ground grain litter. The ground grain litter is composed of a ground grain selected such that when the ground grain is wetted it tends to swell in volume less than 50-100%. In a preferred embodiment, the ground grain litter comprises ground hard red spring wheat used to sorb pet urine and fecal liquids voided by a pet into the litter.
