Meet Mei Lun and Mei Huan. They are the first surviving giant panda twins to be born in the U.S.
Born on July 15, 2013 to Lun Lun and Yang Yang at Zoo Atlanta, the pair have attracted attention nationwide. Seriously though, how could they not? Just look at those faces!
Watch the video above to see their development from day one to day 100. If this doesn't make your Thursday at least a teensy bit better, we don't know what will.
You might be wondering why mom is not caring for both cubs. To answer this, panda caretakers tell viewers that it is because giant pandas are born highly under-developed, and require intense maternal care.
"It’s difficult for a mother to provide this care for more than one cub simultaneously. The best method to ensure that both cubs will survive is to alternate the cubs with the mother for the first few months."
This proven technique was first used in 1990 at the Chengdu Zoo, which housed the first pair of giant panda twins to survive in captivity.
