Look at that face. How could you not love that face? And yet, poor Siku the polar bear was left to die after his mother was unable to produce enough milk to feed the baby. Thankfully, researchers at Skandinavisk Dyrepark in Djursland, Denmark, have been able to bottle feed the little guy and keep him alive. Three zookeepers keep watch over the baby on a 24-7 cycle, and tend to his every need. Siku’s case became a global sensation after this YouTube video of the roly-poly little guy went viral. Watching it, you can totally see why.
