At just a month old, this black-footed ferret kit doesn't fit the description of fierce, but don't be fooled. With a little time and nurturing from the National Black-footed Ferret Conservation Center in Colorado, this sleepy cutie will be ready to be reintroduced to the wild. At about three months old, they are adept at hunting prairie dogs and are about 90% full grown. Black-footed ferrets used to be found through much of western North America's Great Plains, extending from Canada to Mexico. With the help of the Center, U.S. Fish and Wildlife Service, and many partners, these endangered animals are part of a very successful reintroduction program. Their adorable face masks are all unique to the individual, just like our fingerprints. You can see why they're affectionately nicknamed BFFs.
