Zoo Atlanta has released time-lapse video of the first 100 days of their twin panda cubs.
The cubs were born on 15 July and in keeping with Chinese tradition were named on their 100th day - Oct. 23. The twin males are called Mei Lun and Mei Huan, which means something indescribably beautiful and magnificent.
Lun Lun gave birth to the twins on July 15, 2013. The cubs are the first giant pandas born in the U.S. in 2013 and are the first twins born in the U.S. since 1987.
You can watch the pandas live 24/7 via the panda cam at Zoo Atlanta.
