What Do Ferrets Eat in the Wild? Dark-footed ferrets depend on prairie dogs for everything from food to shelter to safety. These wild members of the weasel family eat prairie dogs practically exclusively and also live in abandoned prairie dog dens. They rely on these large holes for protection from eagles and other predators.
For this reason, a ferret diet must be high in animal protein, high in fat, and low in fiber. All foods, including foods intended solely for ferrets, are not created equally, so be careful what you are feeding your ferret. Have Food Available at all Times. Ferrets have a quick metabolism along with a short digestive system, so need to eat frequently (usually every 3-4 hours). It is best to have food available constantly. Most ferrets will eat only enough to meet their needs, and will not become obese if allowed constant access to good quality food.
