Our pets may seem familiar but they exist alongside us in a secret world of wild behavior and natural abilities that we hardly recognize.

From the award-winning team that brought us "Earthflight" and "Penguins: Spy in the Huddle" comes a revolutionary look at our pets.  Our pets may seem familiar but they exist alongside us in a secret world of wild behavior and natural abilities that we hardly recognize.  This two-part series explores this parallel existence with all the techniques that have been perfected in past “spy” shows, including HD spy cameras, night vision cameras, drones, miniature on-board cameras and digital high-speed cameras.
