Meet Mei Lun and Mei Huan, twin baby pandas that were born at the Zoo Atlanta on July 15, 2013. This adorable video shows the first 100 days of their young lives. Giant pandas (Ailuropoda melanoleuca), like all bears, are born blind and helpless. At birth giant pandas are also covered in a thin layer of fur, which is unique among bears. Newborn cubs weigh 85 to 140 grams, their eyes will remain closed for the first 3 weeks and after about 3-4 months they will be able to move around on their own.
