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.
