(WILDLIFE/ANIMAL VIDEO) As a young lion cub, Sirga was orphaned by her pride and rescued by wildlife conservationists Valentin Gruener and Mikkel Legarth. “A pride had three cubs and two were killed before Sirga was abandoned without food,” Legarth told the Daily Mail. “It happened on our land and we could not stand by and watch her die.”

With the Modisa Wildlife Project, Gruener and Legarth are helping save big cats and other wild animals in the Republic of Botswana, which holds the world’s largest concentration of African elephants, among other endangered species. The men make sure Sirga isn’t treated like many lions in captivity, and eventually plan on reintroducing her into the wild. Witness the extraordinary bond between the lioness and the men who saved her. — Global Animal
