Bai Yun seems to be keeping an eye on her cub in this Panda Cam screen shot.

Xiao Liwu is a very different cub from his older brother, Yun Zi, but in a good way. He is very smart and is the youngest cub to respond so well to us keepers. Yun Zi did not start shift training (learning to move on and off exhibit when requested) until he was a little older than Mr. Wu is now (9 months old).

The important thing to have with the training and shifting is a reward (usually food) motivation. Yun Zi enjoyed honey water, and he was really good at following Bai Yun when she went into the bedroom, and after he arrived in the bedroom, he would come to us for his reward for coming inside.

Mr. Wu has plenty of motivation with play to follow us to the shift door, but he has learned that the play ends at the door. And sometimes he seems to just want to be carried to the shift door, so we keepers can do all the work! When he starts eating diet items regularly, he will start being motivated to come inside when asked. Xiao Liwu now weighs 31.7 pounds (14.4 kilograms).
