The bentonite we use comes from mines in Wyoming, where there is a world-renowned high-quality clay. The exceptional properties of this clay give it a superior absorption capacity. It only takes a few seconds for the liquids to clump into solid, compact balls. This makes daily cleaning easier and reduces litter consumption. Available Size: 14 kg
