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.
As to meats, ferrets can have any unsalted, unprocessed meat. So chicken, turkey, duck, other poultry all OK. Fish OK, though if it is canned fish avoid brine or any sauces. And all red meat is also good. But no bacon, no salami, pepperoni or anything else processed or salty. Ferrets are lactose intolerant and should not have cheese, milk or any other type of dairy.
