On the Morning of August 25, 2013, the National Zoo panda team was able to give the cub its first neonatal exam. The cub is robust, fully formed, and is a bright, healthy shade of pink. It weighs 137 grams, which is about 4.8 ounces. Its heart rate is steady, and vets were able to hear breathing sounds from both lungs. It’s belly was nice and full, its mouth was normal, and it was obvious that the cub is both nursing and digesting. All signs are that it is a very healthy, active, vibrant cub.
We won’t know the cub’s sex or its paternity for two or three weeks.
