Tracking outside the box
Compare low-tracking setups
Tracking is a mix of litter particle size, box design, mat design, and static. Use the guide and category pages below before narrowing the field to two products.
Real cost
Compare actual monthly litter cost
Bag price is a weak proxy. Cost depends on clump integrity, litter life, cat count, and how often you fully change the box. Use the cost guide and calculator together.
