It's 3AM, Do You Know Where Your Cat Is?

Humans have a strange relationship with their cats. 

Cats are just about the only pet that some owners allow to roam free when let outside. 

Most people think they know where their cats go and what they do while away from the house, but the truth is that they would probably be surprised to learn what really goes on when the humans aren't around. 

This video by National Geographic talks about some of the things that they are learning about cats by equipping them with cameras and GPS tracking devices while they go about their daily and nightly activities. 

Do you know what your cats are up to when you are not around? Have you attached a similar device to your cat? We'd love to hear your stories in the comments!
