Ollie Norwegian Cat
When we lived in England one of our cats got shut in a garage for 3 days and we had no idea where he was. Once he'd finished his subsequent house arrest we armed all 3 cats with trackers. They have proved invaluable. We are now on our second handset as the old style display gave up and this new version is much better. Since moving to Spain the cats never go out without their trackers on. They don't speak Spanish so can't ask for directions if they get lost!
