Frequently asked questions
What is the cheapest cat litter per pound?+
Frisco by Chewy is the cheapest litter per pound in our tests, at $0.33. A bigger sticker price does not always mean a worse deal - cost per pound is the number that decides which bag is actually cheaper.
Is buying cat litter by the pound better than by the bag?+
Bags come in different sizes, so the price on the shelf cannot be compared directly. Dividing price by bag weight gives cost per pound, which is the only fair way to compare a 20 lb bag against a 40 lb bag.
Does the cheapest litter per pound also cost the least per day?+
Usually, but not always. A litter that clumps weakly or needs a full box change sooner can cost more per day even at a low price per pound, because more of the bag gets thrown away unused.
