How to read this list
Multiple cats multiply scooping, food theft, and vet mysteries. These rankings weight capacity, microchip-level access control, and per-cat running costs. Every card shows two numbers: the sticker and the 3-year true cost. When they diverge hard, that gap is a subscription or proprietary consumables — and it's flagged with a badge. Click through to any device's full receipt for the line items.
If the Litter-Robot 4 doesn't fit your budget — it runs $1,131 over three years — the next tier down, the SureFeed Microchip Feeder Connect ($288) and the PETKIT PuraMax 2 ($759), gives up little where it counts for this use case.
