Pandas have been loaned to various zoos around the world. There are fewer than 50 pandas in zoos outside of China including in the U.S., Scotland, Canada, Thailand, Austria, Mexico, Spain, France, Australia, Japan, Singapore, Germany, Taiwan, Hong Kong, Macau, and soon Malaysia and Belgium.

As a species, they've met a whole host of world leaders and celebrities, including former U.S. Presidents Richard Nixon and Bill Clinton, Queen Sofia of Spain, Shaquille O'Neal and Jackie Chan.

Since the exhibit opened in May, Toronto Zoo's pair of pandas have attracted more than 1 million visitors -- about what the zoo used to do over the course of an entire year.
