Summary
Tens of thousands of five-star Amazon reviews back up its reputation for rock-solid clumps and baking soda odor control. Tracking is a known trade-off, but owners consistently say the odor performance makes it worth it.
Grass seed litter delivers better clumping than corn-based alternatives with zero dust and minimal tracking — and it's not a food crop, so no aflatoxin concerns. Reddit's r/CatAdvice community recommends it as a top clay alternative.

Our take
This isn't the lowest-tracking litter on the list, but if you have a smelly multi-cat home and tracking is a secondary concern, Clump & Seal Platinum is the community's most-recommended clay litter for odor. Pair it with a good litter mat and you're set.
If you want the clumping convenience of clay without the tracking and dust, grass seed litter is the Reddit community's sleeper pick. It's lightweight, clumps tightly, and the granules don't hitchhike on paws the way fine clay does.
