ABSTRACT:
A seed guard that is detachably securable to any bird cage and which deflects thrown seeds back into the cage. The guard includes as many flat, cuttable sheets as there are sides to the cage. The opposite ends of each cuttable sheet are engaged by corner members that are detachably secured to the corner bars of the cage. The seed guard is provided in kit form so that the cage owner may assemble the corner members, attach them to the cage, cut the guard members to size, and slide the guard members into position by inserting the opposite ends of the guard members into detents provided by the corner members.
