As I understand it from the manufacturer this is a provisional formulation aimed at cats. There may be a follow up ferret formula. I didn't intend to give the impression that this was an alternative to raw but rather a better choice of kibble for those possibly older ferrets who will not easily switch to raw (alfafa is only 3.9% carbohydrate) Tony. My home is ferret proof - my heart is not. [Posted in FML 6021]
