Actually quail have a higher fat content than either of them at 31.9%. I have seen only maybe one or two cases of the "cloudy eye" and I am very skeptical on it being because of a rodent diet, as they have less protein than insects of similar size. Phillipe de Vosjoli himself advocates a rodent only diet once they reach adulthood. As stated before, I have an ornata that is going on 7 years of a nearly rodent exclusive diet with zero problems whatsoever, and I remember Ed Clark fed everything he had rodent only diets, including his cornuta.
