When I saw this video for the first time I thought this white cute baby was a puppy – he looks like a pet. But as I went on watching the video I understood it was polar bear cub Knut born on 5 December 2006 in the Berlin zoo. He was rejected by his mother at birth and this is why this man with the beard (on of the zookeepers) took care of him. In these videos you can follow how Knut grew. Today Knut is two years old. Happy birthday, Knut!
