From the National Zoo:

“Mei Xiang and her cub are still doing well! Keepers and veterinarians expect that Mei will begin leaving her den for longer periods of time soon. When she does leave the den for longer periods of time keepers and veterinarians hope to be able to perform another health check on the cub. In the meantime, keepers are continuing to do short training sessions with Mei in her den, and offer her small snack-sized treats for participating.

During the past several days the panda cams have caught some precious moments of Mei and her cub that we’ve pulled together.Thank you to Flickr user dparente for this screen grab of Mei and the cub!”
