Why it matters

Poop Fighter is World's Best's corn-based multi-cat formula aimed at eliminating feces odor rather than masking it. It has a natural, light lemongrass scent.

It clumps quickly with no chiseling, is lightweight and naturally free of silica dust, and the maker says it's flushable and septic safe.

Who it's for, and who should skip it

Good fit if

  • Multi-cat homes
  • Owners who want flushable litter
  • Self-cleaning boxes that take clumping litter

Look elsewhere if

  • Crystal-tray boxes
  • Owners who need the hardest clumps
  • Very high-output cats (can soften)

Pros and cons

Pros

  • Natural corn
  • Quick clumping
  • Flushable (maker)

Cons

  • Lightly scented
  • Corn storage
  • Premium price

Limitations to weigh

  • In a self-cleaning box, use it only where the box's maker accepts clumping litter; most globe and open-top boxes do, crystal-tray boxes don't.
  • Flush only where local plumbing and rules allow.
  • Store sealed and dry.
