Knowing what was eaten, not what was served · review
An RFID feeder that opens only for the cat wearing its tag, logs who ate what and when, and seals 3 L of kibble behind five layers.
What we take from it The only machine in the American survey for this shelf that answers the question the shelf is built on: it knows which cat is eating. An RFID collar tag unlocks the lid, the app logs who ate what and how much, and the lid speed is adjustable for a nervous animal. The catch is in a parenthesis — it works only with the tag in the box, so a lost tag is a feeder that no longer opens.
A feeder with a locking lid driven by an RFID collar tag: it opens for the cat wearing the tag and stays shut for the others. 3 L hopper, 10 meals a day at up to 48 portions each, dual-band Wi-Fi, and a stainless steel bowl. $139.99.
The intro to this page compares machines on how identification works — “collar tag, microchip or nothing at all”. Of the five boxes already published here, two weigh (the Colexy bowl and the Pawsync feeder) and none identifies. A scale can tell you 40 g (1.4 oz) went; it cannot tell you which of two cats took it.
This one can: “see who ate what, when and how much”, logged in the app.
“(Only supports the provided collar tag.)”
That sentence, in brackets at the end of a bullet, is the most important line on the listing. It means:
The buying advice on this shelf is about what survives the dishwasher. Here the fragile part is not the bowl, it is the key.
“RFID-controlled lid and bowl shields ensure peaceful mealtimes and prevent food theft. Ideal for cats with special dietary needs, weight management plans, or medication schedules.”
Medication is the real use. A cat on a prescription diet in a two-cat house is the case where a locking bowl stops being a convenience, and this is the only machine in the American survey that does it.
It does not stop the designated cat from eating its own ration too fast — no feeder on this page does.
Ten meals at up to forty-eight portions each is the widest programming range on this shelf. The Pawsync published here allows ten portions a meal, the PETLIBRO splitter-based feeders fifty. What a portion weighs is not published, which is the usual gap: a portion is a rotor turn, not a gram.
“A sealed lid with silicone gaskets, included desiccant bag, airtight rotor, and RFID-controlled food bowl lid.” The feeders shelf on this site names the hopper seal as one of the three things that decide whether a feeder jams, because softened kibble is what bridges inside a drum. Four of those five layers are seals; the fifth is the desiccant, and desiccant is consumable.
No portion weight in grams, no kibble size range, no read range for the tag, no spare-tag price, and no statement of what happens if the Wi-Fi drops — the listing promises a battery backup on the other PETLIBRO feeders and says nothing here.

The lid stops opening for that cat. PETLIBRO states that the feeder "only supports the provided collar tag", so a generic RFID disc will not substitute and a replacement has to come from the manufacturer — at a price this listing does not publish. Before buying, ask what a spare tag costs and whether it can be paired to an existing feeder, because that is the single point of failure in the design.
No, and that is the line between this machine and the other two on this shelf. It counts portions — up to forty-eight a meal — and a portion is a rotor turn, not a gram; the weight of one is not published. The Pawsync feeder and the Colexy bowl published here weigh, but neither knows which cat is at the bowl. Weighing and identifying are two different machines on this shelf, and this one identifies.
The listing does not give a number, only a principle: each cat wears its own tag and the lid opens for the designated one. The practical limit is how many tags PETLIBRO will pair and sell, which it does not state. What is published is the hopper: 3 L, about two weeks for one cat — so a two-cat household is refilling weekly.
