Overview
["This 10 lb bag of Sustainably Yours litter is made from corn and cassava rather than clay, using a small-grain formula the brand says delivers exceptional clumping and odor control while staying virtually dust free. It's unscented, so odor management comes from the plant material itself rather than added fragrance.", "The small-grain, loose granular texture is also marketed as soft on paws, which can matter for cats transitioning from a different litter type or for households with sensitive-pawed cats. Being corn and cassava based, it's positioned as a more sustainable, biodegradable alternative to traditional clay litter.", "At $21.99 for 10 lbs, it's competitively priced within the plant-based litter category, and with 3,392 reviews averaging 4.1 stars and roughly 7,000 units bought last month, it's one of the more widely adopted natural litters on the market."]

Performance notes
The small-grain corn and cassava formula is designed to clump tightly like clay while producing far less dust, and the loose granular texture is meant to feel gentler underfoot. Because it's unscented, odor control relies entirely on the plant material's natural absorption rather than fragrance masking.
What buyers say
With 3,392 reviews and a 4.1 star average, plus about 7,000 units bought in the past month, this litter has a very large customer base, though its rating sits a bit lower than the top performers in this set, suggesting a generally positive but more mixed experience for some buyers.
It's made from corn and cassava, plant-based materials generally considered more biodegradable than clay, but always check your local composting guidelines before disposing of used pet litter that way.
Does this litter clump as well as clay?
Sustainably Yours markets the small-grain formula for exceptional clumping, and with over 3,300 reviews at 4.1 stars, most buyers seem satisfied, though plant-based litters can clump a bit differently than clay and may take some adjustment.
Is this litter scented?
No, it's an unscented formula, so it relies on the corn and cassava material's natural odor control rather than added fragrance.
