LitterCompare:Cheapest cat litter, ranked by cost per month
The cheapest cat litter is not the one with the lowest sticker price. A small bag that runs out in a week can cost more per month than a bigger bag that lasts. This page ranks every litter we track by estimated cost per month for one cat, next to price per pound, so you can see what each option really costs to live with. Clumping clay is usually the cheapest per month because you scoop and top up instead of replacing the whole box, while premium crystal and natural litters cost more per pound. Sort by cost per month to find the best value, then filter if your cat needs unscented or low dust. Every product links straight to Amazon so you can check the current price before you buy.

Frequently asked questions
What is the cheapest type of cat litter?+
Clumping clay bought in large boxes. It has the lowest price per pound of any litter type, and because you scoop out clumps and top up instead of dumping the whole box, a big box lasts for weeks. In our table the cheapest options per month are all large clumping clays.
Is cheap cat litter any good?+
Often, yes. Several of the cheapest clumping clays we track score 5 out of 5 for odor control. What budget litters usually give up is dust level and tracking rather than clumping or odor performance, so check the Dust column before buying.
What is the cheapest way to buy cat litter?+
Buy the largest box of clumping clay you can store, and compare by price per pound rather than bag price. Big 35 to 40 lb boxes routinely cost a fraction per pound of what small bags cost. Our table does the per pound math for you on every product.
