What do black-footed ferrets eat?
In the wild, prairie dogs make up 90% of a ferret’s diet. A ferret may eat over 100 prairie dogs in one year, and scientists calculate that over 250 prairie dogs are needed to support one ferret family [mom, ½ dad (1/2 dad because not part of the family most of the year but in overlapping territory) and kits] for one year. They may also occasionally eat ground squirrels, small rodents, rabbits and birds.
