Created as a passage that is large enough to accommodate people but not most forms of livestock, a kissing gate is commonly used on farms, ranches, and other facilities that house animals. The idea behind the kissing gate is to allow humans to pass in and out of the space with relative ease, but effectively prevent animals from being able to use the same gate. This is accomplished by a swing action that makes it possible to have the gate closed to the interior when open to the exterior.
