ABSTRACT:
A one way animal gate and barrier fence are described. The one way animal gate includes a smooth, inclined bottom surface surrounded by two sides extending upwardly from the smooth bottom surface. The gate, is placed in an opening in the barrier fence so an animal proceeding along the fence will encounter the gate, step onto the bottom, and be involuntarily slid to the opposite side of the barrier fence. Once slid, it will be unable to return to the original side of the fence due to an inability to gain traction up the smooth bottom surface.
