PETLIBRO RFID Automatic Cat Feeder with 6 Packs Pet Food Desiccant Bag, Collar Sensor for Personalized Meals, Wi-Fi Programmable Food Dispenser with Cats Recognition & Diet Tracking

Each of my cats have electronic food bowls that only open for the. It reads the microchip in their neck (or optionally a chip on their collar). We swapped to them initially because we had one cat that was just never full and we had to put her on a diet.. We also have an old cat that gets prescription food, and another cat that gets higher calories food (due to being underweight) and who only grazes on her food throughout. We have the option of adding multiple cats per bowl, but having 1 per bowl has saved us a few times when we had do to custom food changes. The feeders are a lifesaver. They also make ones that are a combination auto feeder and chip but we do half wet and half dry and that doesn't work with that.
