While the world has been keeping a close eye on the womb-status of the National Zoo’s female panda for some time, cub watch at the Giant Panda Habitat is now officially underway.

A release from the National Zoo updates the panda-loving public on the possible pregnancy of Mei Xiang, who is now being watched 24-7. No, we don’t know if she’s really with butterstick. Yes, she sure has been sleepy lately.

She is spending more time in her den, sleeping and shredding bamboo for her nest, and eating less. She has also occasionally been cradling and grooming her kong toy and boomer ball while in her den. Our veterinarians are still attempting daily ultrasounds when Mei is out of her den, but she has been choosing not to participate.

Even Mei Xiang is already over Cub Watch 2013.
