RFID Collar Tag Recognition——The RFID collar tag ensures that each pet in a multi-pet household has access to its own exclusive feeder, all within one app. It is also key to tracking each pet's hydration amount, duration, and frequency.

Compatible Fountain & Feeder——This RFID Collar Tag is ONLY compatible with PETLIBRO RFID Automatic Cat Feeder PLAF301 and the PETLIBRO Cat Water Fountain PLWF305. (Does not support microchips.)

Dedicated Pairing——Each RFID automatic cat feeder from PETLIBRO is only compatible with only one collar tag. One collar tag can be paired with one fountain and one feeder at the same time; if you have multiple same devices, please use separate tags for each.

Comfort and Safety——The collar features a snap-release design that releases under a force of 6.6lb for added safety. The tag is lightweight at only 0.18oz, making it easy to wear. Equipped with a no-cinch adjustment system that holds the fit in place and prevents accidental tightening.

QR Code on Tag——You can record your contact information through the QR code on the tag for easier reunions.

Collars Included with Every Feeder & Fountain——Each PLAF301 comes with 1 collar, and each PLWF305 comes with 2 collars, built into the standard package. You only need to purchase additional collars if you have more pets or need replacements.
