"It's amazing to see how much she has grown in less than one month," Brandie Smith, the zoo's senior curator of mammals and giant pandas, said Tuesday in a release. "Mei Xiang continues to be a great mom ... and it shows."
Mei Xiang, who has spent much of the past three and a half weeks cradling her cub, finally put the cub down and left the den late Tuesday afternoon. The panda team, which was looking for an opportunity to conduct a full exam, examined the cub while Mei Xiang ate bamboo and drank some water in the adjacent enclosure.
The exam took about 20 minutes.
The cub -- whose has not yet been given a name -- put on some weight since her initial checkup two days after she was born Aug. 23. She weighs slightly less than 2 pounds now -- up from the 5 ounces she weighed at birth -- and has the signature black markings of a giant panda, zoo officials said.
Veterinarians said the cub is 10.6 inches long from nose to tail and 9.8 inches wide around her belly.
