A few hours ago I posted a note saying that a 1.5 pound ferret needs around 75 Kcal daily ( >100 under stress). Although this is roughly how the AMC saw it, and roughly what you get when you plug numbers into a crude formula to calculate caloric requirements, the Fox book has considerably higher numbers - nearly twice as much! I don't know which numbers are correct - perhaps Fox was calculating requirements during activity? (I doubt it) - so just keep in mind that the numbers I gave might actually be on the low side. So, if you wanna fatten up your ferret, perhaps you'll have to work even harder at it now. Bill [Posted in FML issue 0445]
