Debbie-
Are you the original parent of the ferrets that nip from inside the cage?
If not, maybe at some point in their past, they were POKED through the
cage, say by some children in a pet store? Do they still nip you if they
are outside the cage? Maybe they don't realize that you're petting them
from outside the cage; maybe it reminds them of some past unpleasant
cage-related experience.
