hi Becky, It sounds like a great food to me, so I would say definitely add it to the feeding schedule! I just have one question: why use a higher quality food only AFTER a ferret is diagnosed with insulinoma? If you are of the opinion that diet is an important factor with insulinoma (as I am), why not feed the highest quality food you can get, to try and PREVENT insulinoma? (as well as improve their overall health) :) shona [Posted in FML issue 4456]
