National Zoo Giant Panda Mei Xing Pregnant? Final Phase Of Reproductive Cycle Begins
A giant panda at the National Zoo began the final phase Monday of her reproductive cycle, which will reveal whether she will eventually give birth to a cub or if it's a false pregnancy. While the Washington, D.C., zoo did not know if Mei Xing, the adult female giant panda, was pregnant after undergoing several ultrasound rounds earlier this summer, a spike in hormones suggests her reproductive cycle will soon conclude.
