Behavior
Black-footed ferrets spend about 90 percent of their time underground, where they eat, sleep and raise their young in prairie dog burrows. They are nocturnal, and leave their burrows at night to hunt prairie dogs.
Reproduction
Kits are born blind and helpless and stay below ground until they are about two months old. At this age, the female begins to take her young on hunting forays and separates the kits into different burrows. By October, the young are completely independent and will disperse to their own territories.
