LitterCompare:Best clumping cat litter, compared

Clumping cat litter forms scoopable clumps when it gets wet, so you remove only the soiled litter and top up the rest. It is the most popular type because it is easy to clean and usually the cheapest to run. This page compares every clumping litter we track, both clumping clay and natural clumping litters made from corn, walnut, wheat, wood, grass, and tofu, ranked by cost per month and rated for dust, scent, and odor control. Standard clumping clay is also what most automatic litter boxes need. Filter to unscented or low dust if that matters for your cat, and sort by cost per month to find the best value clumping litter.
