Break out the blue! Veterinarians at the San Diego Zoo were elated to discover that their new baby panda, born Aug. 5, is a male. During the little guy's first exam on Sept. 3, zoo staffers were able to determine the panda's sex, as well as weigh and measure him.
In an adorable video posted on the zoo's Web site, a veterinarian called the panda – who's just starting to develop his coloring and has yet to grow teeth – a little "roly poly."
"He was very easy to handle," Zoo representative Jenny Mehlow tells PEOPLE Pets. "Really quiet, even sleepy, vets thought."For now, the unnamed panda is lying low. "He is spending all of this time with his mother, Bai Yun," Mehlow says.
Since pandas are solitary creatures, the cub is not socializing with other bears in his exhibition area, and won't be introduced to the public until his mother determines he's ready. "When she starts leaving him alone for longer periods of time, that will be the indicator that the baby is more agile," explains Mehlow. "We expect that to happen in December or January."
For now, the panda – who will be named 100 days after birth per Chinese tradition – is entering his "cute phase," say veterinarians. We can't wait to watch the little guy grow up!
