Claim:
A removable cup feeder assembly for use on a cage having an entrance door, said removable cup feeder assembly comprising: a dish holder for attachment to a wall of the cage, said dish holder having: a slide rail having an upper section and a lower section, for removably retaining a dish; a vertical stop member for limiting vertical movement of a dish; at least one horizontal stop member for limiting horizontal movement of a dish away from the entrance door of the cage; and at least one cage displacement member for displacing the slide rail from a wall of the cage; and a cup shaped dish having an open end defined by a front wall, a back wall and two side walls, said dish having a flange attached to the open end portion of the back wall by an upper projection member such that the plane of the flange is parallel to the plane of the back wall, said flange and said upper projection member being sized and shaped such that a slide tunnel for slidably receiving the slide rail is formed wherein the tunnel of the dish is slidably attachable to the slide rail such that contact between the flange-projection member assembly and the at least one horizontal stop member limits horizontal movement of the dish away from the cage opening, wherein contact between the flange and the lower section of the slide rail limits rotation of the dish, wherein contact between the flange-projection member assembly and the vertical stop member limits vertical movement of the dish and wherein horizontal movement of the dish toward the entrance door of the cage is limited by the door when the door is closed.
