Abstract
A control device which, when it is installed as part of a fence, allows a small animal to pass from a first side of the fence to the other side of the fence, but prevents an animal which has passed through the device from returning to the first side of the fence. The control device can comprise (1) a mouth which (i) is exposed on the first side of the fence and (ii) has an open cross-section, and (2) an extending passage which extends away from the mouth to an exit. The extending passage can narrow as it extends from the mouth to the exit.
