Learn HOW to avoid them: <http://blogs.webmd.com/pet-tales/2011/09/the-danger-of-xylitol-to-your-dog-and-ferret.html> Notice that this poisoning, like thiamine deficiency from raw egg whites, can be mistaken for a very difficult to treat insulinoma case! This one of the reasons it is so important that a treating veterinarian know what is fed and what might have been gotten into. If you know someone whose ferret appears to have a hard to treat insulinoma case and you know that either of these problems might have happened then alert them, please! It would be a kindness. Remember, too, that a number of flavored cosmetics also have xylitol in them.
