I've seen ferrets from 6 months to 8 years old with a few webbed nails. Some of the younger ones have one webbed nail, versus the older ones. Never heard anything about what may cause this, any suggestions? The few ferrets I saw had the baby nail webbed. Could a ferret be missing something in their diet to cause this? Thanks for any advise. Fuzzybutts [Posted in FML issue 3040]
