You may wonder what your cat gets up to all day – I know I come home to a pile of torn up tissues, and my cat claims to not know what happened. In 2011, engineer Jürgen Perthold equipped his kitty, Mr Lee,  with a tiny camera to capture the day’s events. Perthold was so successful, he was able to edit a 16 minute short film that appeared at the 2012 SXSW, with additional footage shot by Seth Keal. Now Perthold is selling CatCams online, finally solving the mystery of what the heck they do all day (although I might just train my webcam on the tissue box).
