A sun bear cub made a playful first appearance at a zoo in England. The 12-week-old female cub doesn't have a name yet, but she has already made history. She's the first sun bear to be born in the U.K. The animals are native to Southeast Asia and are considered the world's smallest bears. The species is vulnerable to extinction. Her parents were both rescued from poachers in Cambodia. InsideEdition.com's Mara Montalbano (https://twitter.com/MaraMontalbano) has more.
