Famous pygmy hippo Prince Harry dies during surgery

It's a sad day for the Internet's viral animal stars. Prince Harry, the pygmy hippopotamus who saw our heart strings, latched on to them and tugged mercilessly has died. According to the Cango Wildlife Ranch, Harry died of respiratory arrest, which led to heart failure, while in surgery to treat an umbilical hernia. Prince Harry, who can be seen frolicking in the above video, had been rejected by his mother and caretakers at the ranch were optimistic they could raise him. Two other animal online sensations left us this week as well: Meow, the 39-pound cat, died of heart failure, and the tranquilized bear famous for falling out of a tree was hit by a car. Even animal celebrity deaths come in threes.
