Abstract

An animal-actuated feeder (20) has a treadle (26) to be tread upon by an animal (36) desirous of obtaining food, a food compartment (24), a cover (30) with closed and open positions (32, 34) denying and granting access to the compartment (24), and linkage (28) to open the cover (30) when the animal (36) treads upon the treadle (26). A damper (88) is coupled to the cover (30) and dampens transit between open and closed positions (32, 34). A dish (106) having a mating lid (108) coupled to the cover (30) promotes the retention of the food in a palatable condition. A plurality of moat assemblies (118) serve as legs for the feeder (20) and inhibit crawling arthropods from gaining access to the food. A control unit (154) and latch (152) control the opening of the cover (30) in response to a tag unit (162) worn by the animal (36) treading upon the treadle (26).
