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.

Due to the continued high temperatures, we are mainly keeping them indoors in an air-conditioned environment. 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, as with last month, training is underway to keep the pandas' mouths open.
