PrettyLitter is made of super absorbent, lightweight silica gel. Silica gel crystals are extremely absorbent, more so than other litter types, so you need less litter to do the same job. Our long-lasting, non-clumping litter means lighter trash bags, less scooping and less trips to the store. On the other hand, traditional clumping litters turn urine into large (heavy) clumps that need to be scooped out and replaced throughout the month. The super dry silica gels in PrettyLitter absorb the urine and odour, trapping it inside as the water in the urine evaporates out. The solid waste is all you need to scoop and dispose of.
