The National Zoo in Washington, D.C. is eagerly awaiting the birth of a panda cub.

Panda bear Mei Xiang is pregnant and could give birth this week, zookeepers said. The Smithsonian's National Zoo was shuttered for months as a result of the coronavirus pandemic.

“Keep your paws crossed! Today, Zoo veterinarians saw exciting movements during giant panda Mei Xiang’s ultrasound. Her fetus was kicking + swimming in the amniotic fluid, and its spine + blood flow were visible,” the zoo tweeted on Monday. “We hope to have a healthy cub in the coming days!”

Mei Xiang has successfully given birth to three cubs: Tai Shan, Bao Bao and Bei Bei. The three cubs were transported to China at age 4, under terms of the zoo’s agreement with the Chinese government.

Mei was impregnated via artificial insemination, a process that was heavily affected by precautions over the COVID-19 pandemic. The procedure was conducted shortly after the entire zoo shut down on March 14; the zoo reopened on a limited basis July 24.
