The Black Footed Ferret's existence is threatened and endangered mainly due to its main food: the prairie dog being very much reduced in numbers due to hunting and poisoning. And also due to the loss of their prairie grassland habitat and diseace. Since 1967, it has been classified as an endangered species by the U.S. Fish and Wildlife Service. As of 2007, the total wild population of Black-footed Ferrets was well over 650 individuals, plus 250 in captivity. It is the only ferret that is native to America.
