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.
Typically a ferret will eat about 1/4 cup per day. However, this does not include waste (such as if your ferret likes to dig at his food). Some ferrets may eat more, especially the younger ones. Now, you should always have food available to the ferret. Don't just measure out a 1/4 of a cup and give it to him. Keep food in the ferrets dish at all times. Ferrets tend to eat small amounts all throughout the day. If they want to eat more, let them.
