The typical household, not just the cheapest
Ranking by the cheapest litter answers one question; ranking by the middle of the pack answers a more useful one, since most homes are not running the single cheapest brand on the market. Take the middle cost across all 17 tested litters at each household size, and a typical one-cat home lands near $189.80 a year, a two-cat home near $379.60, three cats near $569.40, and four cats near $759.20.
The gap between Frisco by Chewy at the cheap end and Tuft + Paw at the expensive end widens every time a household adds a cat, because the yearly difference between the two brands gets multiplied right along with the cat count. A one-cat household choosing the pricier brand pays $244.55 more a year than the cheapest option; at four cats that same gap in brand choice is worth roughly four times as much.
Questions people ask
How much more does litter cost with 2 cats instead of 1?
On the same litter, two cats roughly double the one-cat yearly cost in our math below, since it scales with cat count. Real two-cat homes sometimes run a bit higher, because a shared box gets scooped and topped up more than a clean multiplier assumes.
What is the cheapest litter for a multi-cat home?
Frisco by Chewy has the lowest one-cat cost in our tests, at $109.50 a year, so it also scales to the lowest multi-cat total. Cheapest is not automatically best for a busy multi-cat box - check its clumping and odor scores before switching.
Does litter cost scale exactly with the number of cats?
Not exactly. We scale cost per day by cat count to get a household estimate, but a real multi-cat box often needs a full change sooner than the math implies, so treat these numbers as a floor rather than a guarantee.
