Our shelter and household has been on a strict Totally Ferret diet for more than 2 years. There is no unwelcome odor from this food. I believe the food you are referring to is the Marshall's Premium food. They use herring meal as a key ingredient in the food. This is smelly ( fishy) in the bowl, in the litterbox and I swear they ( the ferrets eating it) give off a body odor which seems heavier when on this diet. I have also got an openbag of Mazuri in the shelter -- and do not find it offensive either.... of course there is an air cleaner running! If you are this odor sensitive to a mainly chicken / poultry based food I would recommend that you pace it into a plastic tub with an airtight lid, this should help immensely! I hope this answers the question for you. Alicia and a houseful of ferrets [Posted in FML issue 1918]
