Abstract: An integrally formed small animal cage feeder has resilient tabs extending from the side of the feed cup. Each tab comprises a narrow neck joined at one end to the feed cup and at its other end to a head which is enlarged transversely of the neck. The tabs may be deflected and snapped between adjacent bars of a vertical bar cage. In a horizontal bar cage, the tabs may be placed between horizontal bars and, in one embodiment, the head of the tabs turned through ninety degrees to twist the neck of each tab beyond its resilient limit. In a second embodiment, the tab may rest on one horizontal bar and be deflected so that it passes back over the adjacent lower horizontal bar and, due to its resilience, remain so deflected.
