The invention incorporates electronic signals generated from satellites and animal conditioning principles to establish fenceless boundaries to keep animals, like cattle, in a particular area. When the animal attempts to move out of bound, a device–currently a collar worn around the animal’s neck–receives a Global Positioning System (GPS) signal indicating the animal’s exact geographic location. This information is compared to where the animal should be using a Geographic Information System (GIS) contained inside the animal’s collar. The device is programmed to administer bilateral cues to steer the animals back in bound. Virtual fencing, as the system is called, can be programmed to move in time and space, thus facilitating animal containment and distribution. The boundaries can be changed or moved at any time, without expensive labor and materials, based on a producer’s need. For example, a herd can be moved based on vegetation growth patterns, or away from streams and protected land.
