WASHINGTON — The National Zoo in Washington is reassuring fans of the panda cub Bao Bao that she’s doing fine after spending the night in a tree.

Members of the public can watch a live feed online of the zoo’s pandas. When they saw that Bao Bao was in a tree overnight and still there by Wednesday afternoon, they posted worried inquiries on the zoo’s Facebook page.

In a Facebook post to allay their fears, the zoo says Bao Bao climbed the tree after touching a “hot wire” used for animal containment Tuesday afternoon. Zookeepers say Bao Bao’s reaction was predictable and she’s “perfectly fine.”

Bao Bao, who turned 1 in August, is only the second panda born at the zoo to survive to her first birthday.
