mini-site which allows you to track a group of GPS-tagged cats studied in the village of Shamley Green, Surrey, for Horizon's programme The Secret Life of the Cat.
The Horizon team - aided by the Royal Veterinary College and Lincoln and Bristol Universities - tracked dozens of cats over several 24-hour periods using specially-designed collar GPS devices and tiny "cat cams".
The result? Scientists discovered the cats appeared to timeshare territory to avoid confrontation with neighbouring felines and visit each others houses. However, the cat cam footage also revealed squabbles over territory remained. There was also an incident with a fox and with a nest of fledglings.
