Why this pick won
Sustainably Yours blends corn and cassava into a fine-grain litter whose clumps rival Dr. Elsey's for scoopability — rare praise for a plant-based formula. The Plus formula is tuned for multi-cat odor loads. It's light in color (soiled spots are easy to see), biodegradable, and priced like the premium product it is.

What the manufacturer claims
Sustainably Yours's own description, quoted from the product listing. These are marketing claims, not our findings — our assessment is the verdict and tradeoff above.
- OUTSTANDING ODOR CONTROL: Our proprietary formula instantly traps urine odor and prevents its build-up. And we never use fragrance, so there are no artificial scents that can irritate both cats and people.
- EXCEPTIONAL CLUMPING: Because our litter is made exclusively from corn and cassava, it’s naturally rich in starches. This results in dry, fast-forming, and firm clumps that you can trust to stay together while scooping and cleaning your litter box.
- VIRTUALLY NO DUST: Our proprietary machinery removes dust at key points in the production process, resulting in a litter that protects cats from possible respiratory issues—and your home from a dusty mess.
- LOW TRACKING: Larger grains stay in the box better. Our formula creates solid clumps that resist crumbling and scattering, keeping floors cleaner between box visits.
- DESIGNED FOR HEALTHIER CATS & HOMES: Made from corn and cassava with no added fragrances, dyes, or chemicals. Light color makes it easier to spot potential changes in the cat's urine, like the presence of blood.
