Hi all, this is my personal experience on the subject matter. Since three generations - my first couple, their sons and their grandsons - I keep feeding my furries with Iams kitten, with excellent results, males around 2 kg and girls 1.2 in weight. Always dry, canned only when weaning. Every now and then in the past I switched to specific ferret's food (Fluker's, Merrick etc) without noticing any significant difference, but not being always available at my pet shop I definitely switched back to Iams. No other integrators, some Ferretone eventually but mostly as a treat. Fulvio and his 7 devils [Posted in FML issue 3318]
