Stall DRY® Absorbent and Deodorizer is composed of a natural blend of food grade diatomaceous earth and clay in a granular form, which has the ability to neutralize ammonia and absorb odors and moisture. When used daily, can improve your animals' comfort, reduce bedding costs and save labor (clean-up time). It is safe to use on dirt, wood, concrete, metal or rubber surfaces, because it is non-caustic and non-toxic. Can be used with large and small animals.
