Automatic Litter Boxes for Two or More Cats, by Days Between Emptying

With a second cat the drawer, not the mechanism, decides how often you deal with the box. The figure that matters is volume, and only boxes whose maker publishes it are here. Divide it by what two cats produce in a day and the CATLINK Scooper Young Pro-X and 2 others come out on top at about 9 days. 7 of the 31 makers rate their drawer for one cat well beyond what its volume supports, which is why the maker's claim sits beside the arithmetic rather than replacing it.

How this list is ordered: Ordered by days between emptying for two cats: drawer litres ÷ (2 × 0.7 L a day), then by price. 31 of the catalog’s boxes qualify. 2 of them carry a maker safety notice, not a recall — Neakasa M1 Lite Plus, Neakasa M1 Plus — shown on the card and the model’s page.
