Grass seed, not clay — half the weight to carry, and it still out-clumps the heavy stuff.
A clumping litter made from grass seed rather than mined clay — specifically non-GMO food-grade sorghum (milo) grown on US Midwest farms. It clumps because of the seed's own starch content and the way it's extruded under heat and pressure, not because a binding agent has been added.
No added fragrance, no chemicals, no clay, and a claimed 99% dust-free. The grains are soft underfoot, which makes it a reasonable pick for a cat who's fussy about texture, has sensitive paws, or is recovering from a paw injury. It's biodegradable and renewable.
100% grass seed — non-GMO, food-grade sorghum (milo), US-grown. No clumping agents, no clay, no added fragrance, no chemicals.
Fill to a depth of 3–4 inches (roughly 7.5–10 cm) and top back up to that depth after scooping — the litter is designed for a minimum of 3 inches. Scoop daily, but wait about 20 minutes after your cat has used the box so the clump has time to harden before you lift it. Switching over: mix 50/50 with the litter she's used to for the first week, then move to SmartCat alone.
