SAN DIEGO (CNS) - Two 3-month-old Sumatran tigers bounded into their new home Friday at the San Diego Zoo Safari Park.

Joanne and Majel followed their mother, Delta, and explored the three-acre tiger exhibit for the first time.

The Zoo Safari Park, which used to be known as the San Diego Wild Animal Park, is raising funds to build a new forested tiger exhibit that will include climbing rocks, swimming pools, trees and long grass. The new exhibit will put guests at eye level with the big cats and other animals.

Only about 450 Sumatran tigers remain worldwide, making them critically endangered.

The park is home to six members of the species, and 23 have been born there over the years.
