A worker prepares to feed Siberian tigers at the world's largest Siberian tiger park in Harbin in northeastern China's Heilongjiang province in 2008. Eleven Siberian tigers have starved to death over the past three months at a zoo in Shenyang, northeast China, after the cash-strapped animal park fed them cheap chicken bones, according to state media.
