What is claimed: 1. An animal feeder comprising: A collapsible feedbox having an interior void for receiving animal feed; A base attached to the feedbox and configured to rest on a predetermined surface; The base includes a feed outlet for allowing animal feed to be output from the feedbox; and A physical stop is connected to the collapsible feedbox and configured to limit the collapse of the feedbox below the level of feed placed in the interior void. 2. The animal feeder of claim 1 wherein the collapsible feedbox comprises a first concentric band and a second concentric band. 3. The animal feeder of claim 2 wherein the first concentric band has an interior diameter than is greater than the interior diameter of the second band. 4. The animal feeder of claim 3 wherein the first concentric band and the second concentric band are substantially aligned along a common vertical axis. 5. The animal feeder of claim 4 wherein the first concentric band comprises a first flange along the lower edge of the first band and the second concentric band comprises a second flange along the upper edge of the second band. 6. The animal feeder of claim 5 wherein the first concentric band and the second concentric band are configured so that the first flange will engage with the second flange when the first concentric band is moved upward along the common vertical axis. 7. The animal feeder of claim 6 wherein the physical stop comprises a cross member attached to the first concentric band. 8. The animal feeder of claim 1 wherein the collapsible feedbox comprises a unitary vessel that is biased to collapse downward toward the base. 9. The animal feeder of claim 8 wherein the unitary vessel is comprised of an accordion-like wall of flexible material. 10. The animal feeder of claim 1 wherein the collapsible feedbox comprises a unitary vessel that is biased to expand upward along a vertical axis generally perpendicular to the base. 11. The animal feeder of claim 10 further comprising a cover attached to the unitary vessel to counter the upward expansion of the unitary vessel. 12. The animal feeder of claim 1 wherein the collapsible feedbox comprises a spring-like frame and a sleeve for receiving animal feed. 13. The animal feeder of claim 1 further comprising a support system for suspending the base of the feeder at a predetermined level above a predetermined surface. 14. The animal feeder of claim 1 further comprising a motorized spinner plate for broadcasting feed output from the feed outlet. 15. An animal feeder comprising: A collapsible feedbox having an interior void for receiving animal feed; The feedbox comprises a first concentric band having a first interior diameter and a second concentric band having a second interior diameter; The first band and the second band are generally aligned along a common vertical axis; the first concentric band and the second concentric band are configured to engage when the first concentric band is moved upward along the common vertical axis so as to increase the volume of the interior void; A base is attached to the feedbox and configured to rest on a predetermined surface; The base includes a feed outlet for allowing animal feed to be output from the feedbox; and A cross member connected near the upper edge of the first concentric band to preclude the collapse of the feedbox below the level of feed placed in the interior void. 16. An animal feeder comprising: A collapsible feedbox having an interior void for receiving animal feed; The feedbox comprises a unitary vessel biased to collapse downward in a manner that decreases the volume of the interior void; A base is attached to the feedbox and configured to rest on a predetermined surface; The base includes a feed outlet for allowing animal feed to be output from the feedbox; and A physical stop is attached near the upper edge of the unitary vessel to preclude the collapse of the feedbox below the level of feed placed in the interior void.
