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 canât digest dairy products and should never eat them. Avoid giving your pet milk, yogurt, cheese, ice cream or any other type of dairy-based food. Dairy can give a ferret diarrhea, resulting in dehydration and possibly even death.
