The short answer
Split bowls and timed feeders can't stop a fast eater. The fix is a selective feeder that opens only for one cat: microchip feeders such as SureFeed read the implanted chip, and RFID feeders such as PETLIBRO's use a collar tag. Each cat on a separate diet needs its own.
Microchip or collar tag
| Feeder | Opens for | Food |
|---|---|---|
| SureFeed Microchip Pet Feeder | 9, 10 or 15-digit microchip | Wet or dry, 13.5 fl oz |
| Closer Pets MiBowl | ISO and AVID 15-digit chips or ID tags | Up to 340 g |
| PETLIBRO RFID Feeder | RFID collar tag | Dry, timed, 3 L |
| HoneyGuaridan RFID | RFID collar tag | Dry, timed, 4.6 L |
| HEAPETS RFID | RFID collar tag | Wet or dry bowl |
Setting it up
- Register each cat's chip or tag and check the lid opens only for that cat.
- Place feeders apart so cats don't crowd each other.
- Introduce the moving lid gradually; prop it open at first if the maker allows.
Prescription diets
For a cat on a prescription or weight-loss diet, a sealed microchip bowl like SureFeed keeps others out; SureFeed Connect also weighs what each cat eats.
SafetyFollow your vet's feeding plan; a feeder controls access, not portions, unless it says so.

Questions readers ask
Do split-bowl feeders stop food stealing?
No. They serve two bowls but can't stop one cat eating both.
Microchip or RFID tag?
Microchip feeders need no collar; tag feeders need the cat to wear one.
