My little ones love both ferretone and "dog" linatone. In my experience, there isn't any difference between the "dog" version and the "ferret" version, they are both just very heavy, vitamin-fortified oils which should be given only in moderation. Both types have yielded glossier fur, shinier eyes, and all those other things a high oil diet does for a ferret (including a touch of constipation). Both versions have the same strong odor, too - the only difference seems to be the animal pictured on the package. If you could stand the taste, you too could probably get a glossier pelt by drinking the stuff (it's mostly fish oils - yummy!). I've never bought the "cat" version - but I did have two cats turn up their flat little noses at the "dog" version, so maybe there is a difference. Go figure.... Gwen [Posted in FML issue 1641]
