A South China tiger walks in its cage at the Suzhou South China Conservation Base February 2, 2010. Now one of the world's rarest and most elusive of mammals, the South China tiger is a species fully protected by the Chinese government, with none found so far to be remaining in the wild. Suzhou South China Conservation Base is one of the biggest of its kind in China and the largest one with 14 tigers and one seven-week-old cub at the moment.
