World's Best Cat Litter™ traps the liquid and limits the wetness from seeping, sinking to the bottom or sticking to the sides of the box. Clumping on contact also helps keep the rest of the litter dry, so you have less to replace when you scoop. That means fast clumping makes World's Best Cat Litter™ last longer, too! World's Best Cat Litter™ clumps so well you don't have to scrape and chisel like with other litters. Moisture is absorbed in a compact and easy-to-scoop clump. When we clump the benefits together, you get better odor control, more convenience, and a greater value with World's Best Cat Litter™! With its patented formula and quick-clumping abilities, World's Best Cat Litter™ is easy to scoop. Cleanup is a breeze!
