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.
We allow Xiao Xiao to move freely between indoor and outdoor areas, so that she can choose her preferred location depending on the surrounding conditions and weather. If the number of hot days increases in the future, we may restrict her to indoor-only enclosure. There are no particular abnormalities in her feeding or behavior, and she is in good condition.
We primarily feed them bamboo such as Moso bamboo, Shino bamboo, and Madake bamboo, and supplement their diet with panda dumplings, carrots, and apples as needed. We also started feeding them bamboo shoots on April 12th, and they have responded well.
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.

Training animals to exhibit spontaneous behavior is aimed at ensuring their healthy living and safe working conditions for humans.
