An undated photo shows giant panda Yuan Yuan playing at the Taipei Zoo. The zoo has confirmed Yuan Yuan is not pregnant despite earlier showing signs she may have been. The panda's keeper also suspects Yuan Yuan may have pretended to be pregnant to receive the better services, including an air-conditioned single room and superior food, that she was treated to during her last pregnancy. Yuan Yuan was artificially inseminated on both March 26 and 27 when she was in heat. Because the gestation period of giant pandas ranges from 120 to 150 days, the unusual symptoms naturally led to expectations that Yuan Yuan might be pregnant. The symptoms now appear to be fading away. (Photo provided to China News Service)
