Overview
This is a 20 pound bag of SmartCat's grass seed based clumping litter, sold unscented and marketed as chemical and 99 percent dust free. It replaces clay or pellet litter with a plant derived granule for owners who want to limit dust exposure around the litter box.
Grass seed litter clumps differently than clay: the granules bind moisture into a firm mass without the fine clay dust that settles on floors and furniture. SmartCat markets it as unscented, which matters for cats sensitive to perfumed litters, and the plant based material composts more readily than clay. It's also lighter to carry than an equivalent clay bag.
- 20 pound bag, 320 ounces
- Grass seed granule, not clay or pellet
- Unscented
- Marketed 99 percent dust free
Who it's for
Suits owners dealing with dust sensitivity, their own or their cat's, and households that prefer an unscented litter over a perfumed one. It is not the cheapest option per pound compared to bulk clay litter.
Pros and cons
- Marketed chemical and 99 percent dust free
- Unscented formula avoids added fragrance
- Lighter weight than clay per bag
- No scent means it leans on the material alone for odor control
- Costs more per pound than bulk clay litter
Performance notes
Clumping strength depends on the grass seed granules absorbing and binding liquid into a solid mass that lifts out with a standard scoop, the same basic mechanism as clay clumping but from a different base material. Because it is unscented, odor control relies on the material itself rather than added fragrance.
