Mei Xiang at the DC zoo is Tai Shan's mother and if she is pregnant she is due any time now to give birth to her cub.
Now this could be a pseudo (false) preganancy which mimics a real pregnancy very closely in pandas.
She has been picky eating, sleeping a lot and licking on her fur in her sleep,,,,all good indications but only time will tell.
Check out the webcam to follow her progress over the next few days!!!

At the moment this is how she is resting via the panda cam
She just turned over...this is as bad as waiting for our puppies !!!
