I feed mine a mix of Ferret Store (I think original) and Evo dog food, I switch between red meat and regular, they don't like the cat brand and the ferret Evo seems like rebranded cat food at a higher price. I also breed mice for them, I'd love to feed mine raw but food costs where I live are too ridiculous to feed 6 of them. I may start breeding rats next year as well for a larger prey item.
