          Dr Catherine Hauw explained:

                 There are only 6,500 cheetahs in
          the world and their reproductive rates are
          very slow. It is thought that lead decreases
          sperm motility, potentially hindering
          the ability of rehabilitated cheetahs to
          reproduce effectively in the wild.
