01 · Identity
The two identifiers are physically different
An implanted microchip sits under the animal’s skin and carries an identification number. A proprietary RFID tag hangs from a collar and belongs to a particular feeder system.
A feeder can use RFID technology and still be unable to read the chip already implanted in your cat. An existing collar tag is not automatically interchangeable with a different manufacturer’s feeder, either.
02 · Wording
“RFID” is not a compatibility promise
A product title containing “RFID” is not enough evidence of implanted-microchip support. The useful questions are narrower: which exact model, which identifier, and which chip formats?
Zoogrr treats manufacturer documentation as product evidence. Merchant price, stock, delivery and returns are separate offer facts that can change independently.

Three feeders that look similar in search — but do different jobs
| Exact model | Reads implanted chip? | Tag option | Feeder job | Food |
|---|---|---|---|---|
| PETLIBRO One RFID PLAF301 | No | Included proprietary PETLIBRO tag required | Scheduled dispenser | Dry kibble only |
| SureFeed Microchip Pet Feeder MPF001 | Common supported chips | SureFlap collar tag also supported | Selective bowl access, not timed dispensing | Wet or dry |
| Closer Pets MiBowl CP500 | 15-digit ISO/AVID | Closer Pets I.D. Disc also supported | Selective bowl access, not timed dispensing | Wet, raw or dry |
- PLAF301 colour variants do not change the identifier mechanism.
- MPF001 is not the iMPFWT Microchip Pet Feeder Connect.
- CP500 claims here apply to the current MiBowl model and its stated chip formats.
04 · Function
Timed dispensing and selective access solve different problems
Scheduled dispenser
A hopper releases measured portions at set times. The PETLIBRO PLAF301 combines scheduling with access tied to its included collar tag, but it does not read an implanted microchip and it is for dry kibble.
Selective-access bowl
A covered bowl opens when a registered pet approaches. SureFeed MPF001 and MiBowl CP500 control access to food already placed in the bowl; they do not dispense timed portions from a hopper.
05 · Buying check
What to confirm before you choose
- Exact model number. Similar names can refer to different generations or connected versions.
- Identifier language. Look for “implanted microchip”, not only “RFID” or “smart”.
- Supported chip format. Use the manufacturer’s checker or documentation where provided.
- Feeder job. Decide whether you need timed portions or selective access to a bowl.
- Food format. Confirm dry-only versus wet-and-dry use.
- Merchant terms. Recheck price, stock, delivery and returns with the seller.

What this guide does not claim
Zoogrr has not physically tested these feeders. We do not promise perfect exclusion, reliability or veterinary benefit. Placement, pet behaviour and another paired pet nearby may affect opening behaviour.
