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 100%. In 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.
