We began the 20th century with over 100,000 wild tigers. We ended the same century with less than 4,000. Hunted, poached, encroached upon and then slaughtered, the wild tigers of Asia are in trouble and face extinction. But there is a secret number few know: the shocking number of the hidden tigers of North America. There are between 5,000 to 10,000 hidden tigers living in the backyards, roadside attractions, theme parks, zoos, and sanctuaries of The United States alone. Under-regulated, over-bred and often mistreated, these apex predators are born into a lifetime of captivity with a surprising and unintended consequence: their caged existence helps undermine the already difficult task of saving their wild counterparts. The Hidden Tiger is a global exposé revealing the links between captive tigers and the wild tigers’ possible extinction.
