Abstract: An electric fence is disclosed for keeping selected small animals out of an enclosed area. The electric fence has an electrically conductive screen, a plurality of support members for supporting the screen, at least one electrically conductive element positioned adjacent to the screen on a side of the screen opposite the enclosed area, the electrically conductive element mounted to the fence by a plurality of mounting elements, the electrically conductive element being operably couplable to an electric charge generator, and the screen being electrically grounded. The electric fence may be mounted adjacent to a perimeter fence by a distance greater than the distance the selected animal can jump.
