WASHINGTON, DC - AUGUST 25: In this handout photo provided by Smithsonian's National Zoo, the giant panda cub born on August 23 at the Smithsonian's National Zoo receives an exam from animal care staff on August 25, 2013 in Washington, DC. Chief veterinarian Suzan Murray reports that the cub is robust, has a steady heartbeat, a full belly (is nursing well), and has successfully passed fecals [hooooooraaaaay for high fecal marks!]. Zoo officials do not yet know the cub's sex. Animal care staff obtained a DNA sample. It will take approximately 2-3 weeks before the sex is known.The cub weighs 137 grams (about 4.83 ounces).
