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.
Homemade food is another way to feed your ferret. You can feed your ferret cooked or raw chicken along with the pellets. Chicken baby food is acceptable as a supplement to the pellet diet, too. Remember that the dry food is an important staple, as it helps to keep their teeth clean.
