Abstract
An apparatus is provided for containing an animal in a defined area. The apparatus comprises first and second communicating units; one operatively associated with the animal, and the other positioned to locate the area. At least one of the units is adapted to transmit a signal, and at least one of the units is adapted to receive the signal. A circuit is adapted to measure the transmission time or change in transmission time of the signal and calculate the distance between the first and second units. At least one of the first and second units is configured to emit an output to contain the animal in the area when the transmission time corresponds to the animal leaving the area.
