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.
