San Diego zoo

Yun Chuan and Xin Bao are the first pandas to enter the United States in 21 years.

The San Diego Zoo has welcomed two Cheetah cubs to its Safari Park. The nearly three-week-old female cubs are being hand fed and are receiving around the clock care. (Sept. 20)

A male cheetah cub at the San Diego Zoo Safari Park was recovering Thursday from surgery to repair a growth abnormality that caused his legs to bow. The cub, Ruuxa, was accompanied by his friend, a ridgeback puppy, who waited for his return and sat beside him as he came out from under the effect of the anesthesia.

Five-month-old baby gorilla Joanne continues to become more active and more curious at San Diego Zoo Safari Park.

Outside and able to play for the first time - not getting shy on such a big day is a tall order for most giraffe calves.

An abandoned cheetah at the San Diego Zoo was all alone until zookeepers decided to give the little guy a roommate of a different species.
