[Disclosure](https://selfcleaninglitterboxguide.com/affiliate-disclosure/) ## The math - **Total** = box price + (consumables + litter) × 12 × years. - **Box price** is the lowest typical street price on each review page (dated sources), not a live Amazon price. - **Consumables** use each maker's own prices where we could confirm them, at the usage rate the maker suggests. Where a brand's bag price couldn't be confirmed, we use Whisker's $1-per-liner price as a stand-in, which you can change. - **Litter** = pounds per cat per month × price per pound × cats. Crystal-tray boxes skip this line because the tray includes the litter. - **Manual box** = setup cost + the same litter, plus bags if you tick that box. ### Where the consumable prices come from | Profile | Item | Unit price | Basis | | --- | --- | --- | --- | | Whisker Litter-Robot | Waste drawer liners | $1.00 | Whisker: 25 liners for $25. Whisker says the drawer may need emptying as rarely as every 8 days; we assume about 4 liners per cat per month. | | | Carbon filter | $5.00 | Whisker: 6 filters for $30, "1 filter = 1 cat", replace every 2–4 weeks; we use one per cat per month. | | | OdorTrap packs (optional) | $5.00 | Whisker: 6 packs for $30, replace every 2–4 weeks; optional. | | Whisker Litter-Robot 5 (Whisker+) | Waste drawer liners | $1.00 | Whisker: 25 liners for $25; about 4 per cat per month (our assumption from Whisker's 8-day figure). | | | Carbon filter | $5.00 | Whisker: 6 for $30, replace every 2–4 weeks. | | | Whisker+ subscription (optional) | $6.67 | WIRED: about $80 a year; needed for WasteID and reliable cat ID. | | PETKIT PuraMax / Purobot | Waste bags | $1.00 (stand-in) | PETKIT's listing suggests changing bags twice a week for two cats (about 4.3 per cat per month). We couldn't confirm PETKIT's bag price, so we use Whisker's $1-per-liner price as a stand-in; third-party 120-packs are usually cheaper. | | | Odor-eliminator refill (optional) | $6.67 | Stand-in: WIRED cites $20 for three of PETKIT's Purobot Ultra odor refills; we couldn't confirm the N50 price. One N50 lasts about a month (Amazon listing). | | PETKIT Purobot Ultra | Auto-bag rings | $1.00 (stand-in) | Bag-ring price not confirmed; Whisker's $1-per-liner price used as a stand-in at PETKIT's suggested change rate. | | | Odor-eliminator refill | $6.67 | WIRED: $20 for three refills; about one a month. | | PetSafe ScoopFree Crystal | Disposable crystal tray | $24.50 | PetSafe: 3 trays for $73.49 (Nov 12, 2026). PetSafe says one tray lasts about a month for one cat; a Chewy answer gives 10–15 days for two cats. | | PetSafe ScoopFree SmartSpin | SmartSpin liners | $0.72 | Amazon listing: 25 liners, $17.99 list. PetSafe: the 6 L drawer holds up to two weeks for one cat. | | Standard drawstring bags | Waste bags | $1.00 (stand-in) | Stand-in: Whisker's $1-per-liner price at about one bag per cat per week. Third-party 120-packs are usually cheaper; enter your own price. | Litter default: Dr. Elsey's Ultra unscented, 40 lb for $22.99 at Chewy (Nov 2026). The 10 lb per cat per month figure is our planning assumption, not a measurement. Weigh what you actually buy in a month and enter it. Five-year cost for 1 cat Lowest typical box price + maker-priced liners, filters or trays + clumping litter (10 lb per cat per month at $0.57/lb). Optional extras excluded.

Change any assumption in the [cost calculator](https://selfcleaninglitterboxguide.com/tools/litter-box-cost-calculator/). ## A worked example Two cats, five years, default litter. A [PETKIT PuraMax 2](https://selfcleaninglitterboxguide.com/litter-boxes/petkit-puramax-2/) starts at about $390. Its bags at the stand-in price come to about $8.60 a month (4.3 bags per cat), and litter for two cats at 10 lb each is about $11.50 a month. Over 60 months that's roughly $1,200 of bags and litter, so about $1,600 all in. A [Litter-Robot 4](https://selfcleaninglitterboxguide.com/litter-boxes/whisker-litter-robot-4/) at $699 adds liners and carbon filters at Whisker's prices (about $18 a month for two cats) plus the same litter, for about $2,470. A [ScoopFree Classic](https://selfcleaninglitterboxguide.com/litter-boxes/petsafe-scoopfree-crystal-classic/) costs only about $100 up front, but two trays a month at about $24.50 each come to roughly $2,940 over five years plus the box, more than either. A manual box with the same litter is about $690. The takeaway: the cheapest box to buy is often not the cheapest to own, and crystal-tray running costs scale fast with more cats.

Beyond litter, most clumping-litter boxes need drawer liners and some an odor filter. With Whisker's prices (liners $1 each, carbon filters $5 each) a Litter-Robot comes to roughly $9 a month for one cat before litter. PetSafe's ScoopFree Crystal boxes need a disposable tray (about $24.50 each at PetSafe) roughly every month per cat, which includes the litter. ### Is a self-cleaning litter box cheaper than a regular litter box? No. A manual box needs the same clumping litter, so an automatic box costs more over five years: the box price plus liners or trays. What you buy is time and a cleaner box between scoops. The calculator shows the gap for your number of cats. ### Do self-cleaning litter boxes use less litter? Makers often say so, but we couldn't find independent measurements, so the calculator assumes the same litter use per cat for automatic and manual boxes. If you know your real usage, change the pounds per cat per month. ### Why are crystal-tray boxes so expensive to run? The tray is the litter and the waste container in one, and it's thrown away when full. PetSafe says one tray lasts about a month for one cat, and a Chewy answer gives 10–15 days with two cats, so costs scale almost directly with the number of cats.
