Overview
["World's Best Cat Litter is made from ground corn rather than clay, and this Poop Fighter version is formulated to target odor from both urine and solid waste specifically, with a light lemongrass scent layered on top. It's sold in a 15 lb bag from Kent Pet Group, a long running litter manufacturer.", 'At $21.35 for 15 lbs, it lands in the mid range for corn based litters, which typically run a bit more per pound than basic clay but appeal to owners looking for a lighter, more sustainable material. Corn litters generally still clump, giving a similar day to day scooping routine to clay.', 'With 2,100 reviews and a 4.3 star average, plus roughly 6,000 units bought in the past month, this is one of the more established and higher volume litters in this batch, and its Best Sellers Rank of #45 in Cat Litter backs up its popularity.']

Performance notes
The corn base gives this litter a lighter feel than clay while still supporting clumping for routine scooping, and the Poop Fighter formulation adds targeted odor control for solid waste on top of standard urine odor handling, a combination meant to address the two main smell sources in a litter box. The light lemongrass scent adds a mild fragrance layer rather than relying on unscented odor absorption alone.
