Like all newborn pandas, the cub is pink, hairless, and about the size of a stick of butter. Officials will follow Chinese custom and give it a name after 100 days.

Mei Xiang gave birth to her first and only other cub, a male named Tai Shan, in 2005. Since 2007, zoo officials have had five unsuccessful attempts at artificially inseminating Mei Xiang.

For now, keepers said, Mei Xiang is doing well and responding to the cub’s fussy grunt and high-pitched squeal.
