Feeding carnivores live quarry is a growing attraction in China, where sightseers can watch aligators chomp chicks, lions mangle goats or big snakes swallow rats. But none of the entertainment is as popular - or as misguided, say some animal experts - as the killings at China's Siberian Tiger Park. The part is supposed to be a scientific endeavor to teach tigers bred in captivity how to hunt for themselves in the wild. But money is tight, so the park sells prey to tourists who watch the cats kill to order. Want to see a Siberian tiger make a pig squeal? It costs $120.
