This special ferret is one of the most endangered species in the whole United States. It only lives in the Great Plains and some parts of the Canadian Territory. Also, when the Native Americans were around, they used them to make pelts, clothes and are used in special ceremonies. In Nebraska, they were all killed by many of the ranch dogs that lived there.There are not a lot of these fantastic ferrets out there anymore. There are only about 1,000 of them left in the wild today. Also, they are part of the three ferret species that live on this planet today. The other two are the Siberian polecat and the European polecat. But out of those two, they are the only ones that live in North America. In addition, they have been classified as an endangered species since 1967.
