A pig that survived 36 days trapped under the debris from the Chinese earthquake has doubled in size since his rescue. The pig lost two-thirds of its body weight while he was trapped, when he survived by eating charcoal and drinking rainwater. Named Zhu Jianqiang, he has since been adopted by a museum where he has become the most popular attraction. Curators say Zhu is recovering well and has a new playmate, a goat which also survived the earthquake. He has already doubled in size from 50kg to nearly 100kg.
