World's Best Cat Litter Clumping Formula is an all-natural litter made from whole-kernel corn. Why Corn? Corn has a unique microporous structure that provides a large surface area to effectively trap and absorb ammonia. By using Corn, it's safe for both cats and kittens without worrying of ingestion, dust or allergy problems. World's Best Cat Litter is 99% dust free, containing no clays, silica, synthetic binding or dust reducing agents found in other litters.
In all, World's Best Cat Litter is safe, natural, clumpable, scoopable, flushable - best of all it's earth-friendly and septic safe!
NOTE: Do not expose kittens to litter before they are 8-weeks of age.
