Pet feeder uses RFID to admit only authorized cats and dogs

Do you have a greedy fat cat who likes to steal the food from all your other pets' bowls? This feeder could be the answer, with a locked door that only opens when the right cat steps up for some chow. Using the same RFID technology as those electronic pet doors, the Gatefeeder cat feeding system has a flap door that only opens when the cat wearing the right RFID tag collar approaches the feeder.
