This Feeder Controls Your Fat Cat's Portions

If you've got multiple cats at home, the Gatefeeder makes dinner time easier if one of your felines is on a special diet: only a cat wearing a unique RFID tag can squeeze through its door and dine.

An electro-magnetic lock prevents the door from opening when the RFID tag isn't nearby, blocking access to other pets, and even kids, who aren't supposed to be eating what's inside. And it provides a quiet place for skittish cats who need to eat in peace.

The Gatefeeder can also be used for portion control, letting you serve up a specific amount of food for each one of your cats depending on their weight. But at $US250 it's a cost-prohibitive solution if your entire home is crawling with felines. [Gatefeeder via Cool Hunting]
