Abstract:

An animal feeder and animal feeding system is provided that utilizes radio frequency identification technology to permit animals selective access to food. The animal feeder includes a universal base containing all of the necessary control electronics including a radio frequency transceiver and antenna. A given number of pre-defined codes are associated with sets of removable dishes and transponders. The transponders are arranged for attachment to an animal. All dishes and transponders in a given set are associated with the same code and can be used interchangeably. The dishes are sized and shaped to be fit into the base, and while a given dish is disposed in the base, the dish communicates or programs the control electronics with the pre-defined code associated with the dish. Therefore, when an animal wearing a transponder from the same set as that dish approaches the animal feeder, the control electronics recognize the animal and open a lid to permit access to the food contained within the dish.
