PETLIBRO One RFID Smart Feeder Review: One Tag per Feeder, One Cat per Bowl

The feeder pairs with a single collar tag. PETLIBRO's product page says it plainly in its FAQ, and the pre-sale answers repeat it: each feeder can be linked to one collar, and spare tags are sold separately. So the tagged cat owns that bowl, and every other cat is locked out of it.

That solves a specific problem well. A cat on a weight plan, a renal diet or a prescription kibble can eat its own food on its own schedule while a greedy housemate is kept away. It does not solve the other common problem, a shared feeder that hands each cat a different portion. For that, two cats need two feeders and two tags, and PETLIBRO sells the feeder in two-packs and three-packs for exactly this reason.

Placement follows from it. PETLIBRO asks for at least 10 inches (25 cm) between One feeders and 5.9 inches between a feeder and a Dockstream fountain, because the reader mats can interfere with each other. Its support page lists nearby metal and electronics as the first suspect when the lid closes slowly, so a row of feeders along a kitchen wall needs some planning.

The reader works only with PETLIBRO's own tag. It does not read implanted microchips or tags from other brands. That is the difference from Sure Petcare's SureFeed, which reads the chip a cat already has, and it means the cat has to wear a collar every day.

The tag itself is small and needs no charging. PETLIBRO lists it at 4.2 g, about 0.9 by 0.9 by 0.55 inches, splashproof but not for submerging, on a snap-release collar. It carries a QR code that can hold your contact details. Cats.com's reviewer still found it a little bulky for a cat, and pointed out the catch with any breakaway collar: when the collar opens, the tag goes with it, and the cat loses access to its food until you find both.

For a cat that will not tolerate a collar, this feeder cannot work. Our guide to what a microchip can and cannot do explains why the chip a vet implanted is a different technology from an active tag.

The bowl sits under a hinged lid with clear shields on both sides. When the tagged cat steps onto the reader mat, the lid opens. It closes when the tag leaves the reader's range, and an infrared sensor stops it from closing on a head or a paw: if something blocks it, the lid reopens briefly and tries again, and after three failed attempts the app sends a notification.

That safety behavior is also the gap. A second cat that pushes in while the first is eating, or arrives the moment the lid starts to close, can reach the food, and the feeder has no mode that shuts the bowl against an approaching untagged cat. Cats.com found the closing speed a little inconsistent without calling it a real problem. Several commenters under that review describe something worse: lids that took many seconds to close, and young cats that learned to pull the lid off its hinge within a day.

Treat it as a strong deterrent, then, and set your expectations by the cats you have. A determined, food-motivated cat is exactly the case where it is weakest.

Setup runs through the PETLIBRO app. The manual warns that a second app, PETLIBRO LITE, sits next to it in the stores and is the wrong one. The feeder takes up to 10 meals a day, and Cats.com found portions as small as 1/12 cup and called the app easy to navigate. Each visit to the bowl shows up in the log with a time and how long the cat ate, which is the part a vet will ask about.

The feeder works without a subscription. PETLIBRO Care is an add-on with trend charts, goal setting, multi-pet dashboards and device replacement, sold in a Standard plan for one pet and a Plus plan for several. Nothing in PETLIBRO's documentation makes schedules or the lid depend on it.

Three alkaline D batteries, not included, keep meals going through a power cut. PETLIBRO says not to use rechargeables or to run on batteries alone. Its website and FAQ say Wi-Fi switches off in battery mode while schedules continue, and the manual says the RFID, Wi-Fi and feeding functions stay on. Plan for the cautious version. Our piece on smart feeders when the internet drops covers what keeps working.

Only the stainless bowl goes in the dishwasher. The base gets a damp cloth, and the desiccant bag under the lid is due every 14 days. The 3-liter hopper takes dry kibble from 2 to 15 mm, and PETLIBRO suggests the feeder for cats and small dogs.
