I was trying to make the math easier, not even more technical than it already was. While your correction is absolutely accurate, you only managed to confuse the reason the post was made, which will make those for whom it was intended likely to disregard its validity altogether. The point is simply: Use the NEEDED ingredients. This has been a constant and repetitive problem with recipes posted for "the good" of the ferrets that has, in many cases, contributed to poorer nutrition, and "medicinal" soups that in fact are serious health risks for ferrets with insulinoma and digestive tract problems. Just because something's fancy and complicated DOESN'T make it better. Keep it simple. I'm not a doctor, a nutritionist, or (obviously, LOL) a math wizard.
