Do Larger Cat Litter Granules Really Reduce Dust and Tracking?
Yes, larger cat litter granules usually reduce tracking, but they do not automatically eliminate dust. If litter is scattered mainly around the box, choose a heavier, less clingy formula; if a visible cloud appears when you pour or scoop, look for a formula that also controls fine particles and forms firm clumps.
Why larger granules usually track less

Tracking happens when particles leave the box on paws, fur, or scattered litter. Fine, light particles are more likely to cling between toes, settle into carpet, or travel when a cat digs. Larger and heavier granules give paws and fur fewer small particles to carry, so the trail outside the box is often shorter.
Granule size cannot stop litter that is flung during digging.
Why dust is a separate question
Dust consists of fine particles suspended in air, which litter can release during pouring, digging, scooping, or clump breakage. Larger granules may create less visible dust because they contain fewer very small pieces, but the complete formula and manufacturing process matter too.

A litter can have relatively large pieces and still become dusty if it breaks down during use. Conversely, a mixed formula may contain different particle sizes while producing little visible dust when it is handled gently. Look for low-dust processing, strong clumps, and limited crumbling rather than relying on granule size alone.
