To get an accurate weight for a pet as small as a ferret, you will need a baby scale. This is what our vet uses, and it works just fine. I'm not sure where you could find them, but you might try a medical supply store. To describe in in detail -- this is a scale made for human babies. You may have seen one if you've ever been in a pediatrician's office. It is a scale with a wide, bassinette-like "holder" for infants. This works great with small animals. -Tasha "It has been said that man is a rational animal. All my life I have been searching for evidence which could support this." -- Bertrand Russell [Posted in FML issue 2078]
