A dog is wrapped for sale at a market in the Baiyun district in China's southern city of Guangzhou. In this dark, foul-smelling market, traders have just about anything to offer from birds and waterfowl, domestic dogs and cats, to the exotic flying squirrels and leopard cats. What cannot be supplied legally from farms is hunted from the wild, or imported, as well as smuggled, from overseas. (Kin Cheung/Reuters)
