PETLIBRO is best known for automatic feeders that dispense food on a schedule. That works fine for single-cat homes, but multi-cat households have a different problem: one cat usually eats everything. The RFID Cat Feeder 3L Wi-Fi solves that by only opening for the cat wearing the included collar tag. It locks the lid until a specific cat approaches, so the grazer gets their portion and the food thief gets nothing.

The feeder uses a lightweight RFID tag on the collar to trigger the lid mechanism. You can adjust how fast the lid opens in the app, which helps skittish cats adapt. The 3-liter hopper holds enough dry food for several days, depending on portion size. Through the PawSense system, the Petlibro app logs exactly which cat ate, how much, and when. That data is useful if you are tracking a cat’s appetite for health reasons or just want to confirm the picky one actually ate dinner.

The main limitation is the single-tag system. The feeder only works with the included RFID collar tag, so you cannot use third-party tags or microchips. That means every cat that needs access must wear the PETLIBRO collar tag. If your cat refuses collars, this feeder will not work for you. For everyone else, it is a practical solution to a common multi-cat feeding headache.
