Secret life of the cat by BBC News Visual Journalism team

What does your cat get up to once it leaves the cat flap? BBC Horizon teamed up with the Royal Veterinary College and Lincoln and Bristol universities to investigate the secret life of domestic cats. The challenge was to use the GPS tracker and cat cam data in an interesting and engaging way that would fit the subject. Wanting to make our content fun as well as educational, journalist Lucy Rodgers and designer Helen Sears we decided to arrange the information around 10 of the cats tracked by the research team.
