Lucky Exam 13

Yesterday was Xiao Liwu’s 13th exam. Thirteen might be unlucky for some people, but for me it was my second opportunity to assist with an exam; my first one was six weeks ago (see post Panda Cub: Exam 7). It was definitely a different experience this time around. To start, we now perform the exam on top of a special carpet on the ground in the Giant Panda Research Station. This transition happened a few weeks ago when the young cub began attempting to crawl. He was an adorable wiggly worm as I tried to hold him still while the veterinarian and nutritionist attempted to examine and measure him.

At 15 weeks of age, he weighed 10.3 pounds (5.7 kilograms) and is 25.1 inches (64 centimeters) long (see growth chart below for a cub comparison), and our veterinarian, PK Robbins, noted that his first four teeth have erupted through his gums.

The best part is that his crawling seemed to bring him up into my lap, not away from us as one might expect. It appears that our sweet panda baby enjoys a good cuddle! At the end of the exam, we backed away to observe the improvement in his crawling with no impediments. Xiao Liwu is progressing nicely, getting his rear feet under him as he crawled. We have even witnessed him crawling back into the den, which is raised about 6 inches (15 centimeters) off the ground.

Stay tuned for future milestones!

Panda Cub Exam 5: Say Aww

I can almost see you now!

The Giant Panda Team at the San Diego Zoo completed another exam on our little cubbie this morning. The calm, 53-day-old cub didn’t make a peep while he was weighed, measured, and examined by veterinarians. While being scratched behind his ear, it triggered a super-cute kick reflex in his leg that had everyone in the exam room saying “aww.”

The newest cutie weighed 4.9 pounds (2.26 kilograms) and is 16 inches (42 centimeters) long. Veterinarians noted that his eyes are almost open now. They believe the cub has some vision, but it is likely limited to light and shadows. His chest now measures 12.5 inches and his well-fed belly is 14.5 inches around.

Bai Yun has started taking her boy out of the den and into her attached bedroom area while she eats bamboo, so don’t be alarmed if you check in on Panda Cam and find the den empty. She’ll return him soon.

Members of the Panda Team have nicknames for the cub, but we are still taking suggestions for the cub’s official name through Monday, September 24. Just click here to submit your name idea!
