We use a mix of foods for our personal ferrets from Iams Kitten and
Totally Ferret and 8 in 1 Ultimate and Evo. We mix it so that if any
formulas change there is still something in there that they're familiar
with. I am sure others will tell you... when ferrets don't like a new
food, they might STOP EATING COMPLETELY.
