How to read this list
These devices never bill you monthly: no required plan, no optional paywall holding features hostage. The only recurring cost is honest consumables — and we price those too. 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 Microchip Pet Door Connect doesn't fit your budget — it runs $265 over three years — the next tier down, the SureFeed Microchip Feeder Connect ($288) and the PETLIBRO Granary WiFi Feeder ($162), gives up little where it counts for this use case.
FAQ

Our cost-weighted ranking puts the SureFlap Microchip Pet Door Connect first (PetScore 87): no subscription, about $265 total over three years — stray-proofing the cat door.
How are these rankings calculated?
Every device in our database carries the same cost model (device + subscription + consumables) and a PetScore; this list re-weights for the use case (no subscription). No sponsorships, no pay-for-placement — the weights are documented on our methodology page.
Do these rankings include subscription costs?
Yes — that is the point of this site. Each pick shows its 3-year true cost including subscription midpoint and consumables, and required-subscription devices are flagged with a SUB REQUIRED badge.
