An abandoned Siberian tiger cub is "cared" by a goat at the Jiufeng Forest Zoo in Wuhan, capital of central China's Hubei Province, Nov. 14, 2010. It is estimated that there are merely 50-60 wild tigers surviving in China. More tigers are artificially bred in captivity. The wildness of those tigers raised in captivity has degenerated, thus leading to difficulties for their natural mating and wild living. They have become too familiar with humans and lost their natural wildness. [Xinhua]
