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.
Ferrets on dry diets must have a constant supply of water. The volume of water required is about three times the volume of dry pellets eaten. In warm weather they drink much more. Ferrets that have no water for 24 hours will stop eating. Water bottles are a convenient way to keep clean water available, but ferrets prefer to drink from a dish and will drink much more from a dish than from a bottle.
