How we pick the best cat litter
The price on the bag does not tell you much. A cheap litter that runs out fast can cost you more than a pricier one that lasts. So we put every litter on the same footing, price per pound and an honest estimate of what it costs per month, and let you filter by what your cat actually needs: clumping or not, unscented, low dust, odor control, robot compatibility, and health monitoring. The best cat litter is usually not the most expensive one.

Between $0.47 and $3.57 per pound across the 32 litters we track on Amazon, with the average at $1.90. Per bag that is $9.99 to $59.00 depending on size and material. See our cat litter cost page for the full breakdown by type.
How much does cat litter cost per month?+
For a single cat, roughly $7 to $38 per month depending on type and brand. Budget clumping clay is the cheapest and premium crystal and natural litters the priciest. The $/mo column ranks every litter on that basis.
What is the cheapest cat litter?+
Right now the cheapest litter we track is Arm & Hammer Slide Multi-Cat Unscented Clumping Clay Cat Litter, 38 lb at $0.47 per pound, about $6.63 per month for one cat. Large boxes of clumping clay are almost always the best deal; our cheapest cat litter page keeps the full ranking current.
What is the best cat litter for odor control?+
For strong odor control, look at premium clumping clays like Boxiecat, Arm & Hammer Slide, and Fresh Step Heavy Duty, which we rate 5 out of 5 for odor. Sort by the Odor column to see the strongest. Health-monitoring crystals like PrettyLitter also hold odor down well.
What is the best low-dust cat litter?+
Natural litters (walnut, wood, tofu) and premium low-dust clays such as Boxiecat and Arm & Hammer Slide tend to run cleanest. Use the Low-dust filter to see only the cleanest-pouring options, then sort by cost per month.
Is clumping clay or crystal litter cheaper per month?+
In our table, clumping clay runs $7 to $21 per month for one cat, while crystal lands between $16 and $29 because it costs more per pound even though it lasts longer. Clumping clay is normally the cheaper choice. Sort by the $/mo column to confirm for the exact products.
What cat litter works with automatic litter boxes like the Litter-Robot?+
Most automatic and self-cleaning boxes need standard-weight clumping clay to sift correctly. Use the Robot-safe filter. Lightweight, crystal, and non-clumping litters are generally not recommended and can jam the mechanism.
What is health-monitoring cat litter?+
Litters like PrettyLitter and Tidy Cats Tidy Care Alert change color with your cat's urine pH to flag possible urinary issues early. Use the Health monitoring filter to see them. It is an early warning, not a diagnosis, and never replaces a vet.
