When Tiger the cat bolted out of a window in 2002, his owner searched unsuccessful throughout her neighborhood in Southam, England. She finally gave up, imagining the worst had happened.  But six years later she got a call from a veterinarian in Cambridge, 100 miles away.  Her pet had been found and could return home, thanks to the microchip that had been implanted in Tiger as a baby. Tiger was reportedly older and wiser since last seen but was not talking about what he'd been doing for six years on the road.
