How wide the spread really is
Cost per pound runs from $0.33 on Frisco by Chewy up to $4.00 on PrettyLitter. The middle of that range, across all 17 tested litters, sits at $0.67 a pound, so a bag priced near the top of the table is not a rounding error, it is about 6 times what the median bag costs for the same pound of litter.
10 of the 17 litters here come in a bag heavy enough to count as warehouse size. A lighter bag being cheap per pound does not make it cheap to own, since it runs out sooner and sends you back to buy another one. 16 of the 17 products have a measured dust reading, which is the number to check next if a cheap bag also needs to be a low-dust one.

Questions people ask
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.
