Panda Cub: The Den

A boy and his moat!

A boy and his moat!

As of January 17, Bai Yun showed us keepers that she is done using her den. How? By leaving a fecal sample in there. When this happens, we clean the den (remove the bedding and disinfect the floor) and close the den door for good. Xiao Liwu is now old enough where he will be spending most of his time high in the trees with Mom.

Some of our panda fans have been curious to know about our panda cub’s nursing activity. Xiao Liwu and Bai Yun both decide with he nurses these days. He seems to nurse early mornings and early evenings. I am sure he nurses throughout the day, as we are not always watching, but it’s not on a regular schedule, since he nurses when he wants to!

We do weigh him regularly and have the nutritionist look at him to body score him. The body score is a great tool to measure body fat and hydration levels. At his exam on January 15, Xiao Liwu weighed 17 pounds (7.8 kilograms) and measured 33 inches (85 centimeters) long.

One of our readers asked if baby pandas shed their coats, like human babies get new hair later on? When panda cubs start getting fur, it has a slightly pink tinge to it. We call it “baby fur.” As they reach around 5 to 6 months, the pink fur does grow out and shed. Have any of you noticed this with Xiao Liwu?
