Bentonite is used for cat litter, due to its advantage of absorbing refuse by forming clumps (which can be easily removed) leaving the remaining product intact for further use.

Cat litter made from natural sodium bentonite has properties of being highly absorbent and absorbs the cat's urine instantly; its granules immediately contract to be form 'a clump' (which is easy and convenient to clean from the tray). Bentonite also has a natural property to kill odor so will control the urine odor; moreover bentonite does not allow bacterial growth in the litter tray. Lastly and most importantly, bentonite does not cause any harm to cats' skin. When you use moderate size granules of sodium bentonite (0.5 mm to 2.0 mm) the litter does not stick to the cats' paws and avoids tracking in the house.
