We would like to announce the following about the two Giant Panda Xiao Xiao and Lei Lei, who were born at Ueno Zoo on June 23, 2021.

Xiao Xiao's latest news

Xiaoxiao's health is good.

As the weather has become cooler, we are allowing the animals to move freely between indoors and outdoors on colder days. There are no particular abnormalities in their feeding or behavior, and they are in good condition.

They are fed mainly bamboo such as moso bamboo, shinotake bamboo, and Madake bamboo, with side dishes such as panda dumplings, carrots, and apples given as needed.

Xiao Xiao has been undergoing Eurasian Moorhen training (*) since July 16, 2023. Through repeated training, it will become possible to safely manage the health of pandas by touching them with minimal stress. Training was temporarily suspended when Ri Ri and Shin Shin went into quarantine, but resumed on October 25, 2024, after their return to China. Currently, she is largely able to maintain an open mouth position, which she was training until last month. Going forward, she will practice regularly to maintain the ability to perform the necessary movements when needed.
