Healthy and well fed! That was the ruling animal care staff gave to Nababiep's two-and-a-half-week-old cubs during their first veterinary exam yesterday. The complete physical involved listening to the cubs' hearts and lungs; checking their mouths, eyes, legs, and feet; and feeling their bellies. Both cubs weigh in at about nine pounds. Keepers gave the cubs a touch-up on their identifying shave marks (one on the shoulder, the other on the base of the tail). As the cubs continue to grow and develop, animal care staff will be able to determine whether we have boys, girls, or one of each!
