Four white tiger cubs get milk from a dog at Xixiakou wildlife protection area in Weihai, East China’s Shandong province on May 21, 2011. An 8-year-old white tiger mother gave birth on Friday morning to four cubs belonging to a relatively rare species after she gave birth to quadruplets last September. Because the white tiger mother cannot feed her babies well, the workers always find a dog mother to feed them. [Photo/Xinhua] |
