A substantially animal-proof barrier (“APB”) that includes (a) two supports that are laterally spaced apart to define a substantially vertical plane there between； (b) fencing material that is attached to each of the supports and spans the defined substantially vertical plane to form a simple barrier that has a top edge, a bottom edge, a front surface and a back surface, wherein the simple barrier divides a domain into a first area and a second area； and (c) a hood having an inner surface, the hood originating from the top edge of the simple barrier is described. An angle formed by the inner surface of the hood and the front surface of the simple barrier measures about 10 degrees to about 80 degrees, such that a channel having a substantially V-shaped cross section is formed.
