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.
03 · Current UK examples
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 | Timed dispenser plus tag-controlled bowl access | 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.
Choosing between them
PETLIBRO One RFID vs SureFeed: which suits your cat?
Want to use the implanted chip without a collar? Compare SureFeed MPF001 with MiBowl CP500. The PETLIBRO PLAF301 cannot read that chip.
Want measured dry-food portions on a schedule? PETLIBRO PLAF301 can dispense them and restrict access using its supplied tag. SureFeed and MiBowl hold food you put in the bowl; they do not dispense portions on a timer.
Just want to control who reaches dry food? All three may be candidates if a compatible collar tag is acceptable. Owning a microchipped cat does not prevent you choosing the tag option. For wet food, exclude PLAF301.
These are specification-based distinctions, not hands-on test scores. In particular, PETLIBRO’s support guidance describes situations where another pet obstructs the lid and it cannot close: selective access is not a guarantee against every attempt at food stealing.

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.
