Gerald, you might consider a fish weighing scale. I bought mine at WalMart for less than $20. It has a digital/electronic readout and is accurate with my vets scale. I put a ferret in a plastic grocery bag with handles, hang on the scales hook, and read the weight instantly. Best to weigh a sleepy ferret as they think this is great fun and can bounce around a lot making it harder to get the weight quickly. Ardith [Posted in FML 6427]
