We all really already know the recommended protein and fat for the foods we feed our ferrets but that doesnt do much good if the ferrets wont eat it. My first "business" of ferrets I fed Iams kitten. When I obtained my second "business," after being enlightened to use a mixture, I used ferret store original, zupreem and a little Iams kitten mixed in. The old "business" picked out the Iams and left the rest. The new "business" of course ate the mixture no problem. I should add "business" # 2 is mainly young ferrets. "Business" # 1 is now down to 1 ferret (Loopy) and she is on a chicken gravy. I have purchased a bag of the new natural gold for her because of her Insulinoma and am trying her with it. It wont do her much good though if I cant get her to eat it which I cant tell yet. I have it in her cage for in between chicken gravy. I dont think the saying, "they will eat it if they get hungry enough" applies to ferrets. Rita B. [Posted in FML issue 4428]
