Nairobi and Sahara were born in a litter of five cubs at the Dickerson Park Zoo in Springfield, Missouri. The two were transfered to Birmingham in 2005 and then went together to the Memphis Zoo in Memphis, Tennessee in 2008.
Siblings Akila and Bastet remained in Springfield. The fifth cub died at birth.
