Ever wondered what cats spends their time doing when the owners are not around? Where do they go when they disappear through the cat flap? Armed with GPS tracking devices and micro-cameras, a team from BBC Two's Horizon program in collaboration with the Royal Veterinary College set off to a Surrey village to find out. In this visualization the users can check each of the cats, information about them such as age, sex, breed/color, character, etc. and check their journeys. The visualization also provides short videos about key events in their journey.
