Hello.  My ferret Jillie developed what looks like a blister on the side
of her rear leg a couple of months ago.  It was a clear liquid filled
bubble.  The vet drained it and said it might fill again.  Which it did,
she drained it a second time saying it shouldn't happen again.  Well,
about two weeks ago it did, and the vet drained it a third time.  I just
noticed tonight it is filling back up.
 
Any ideas?  It doesn't bother Jillie, even when I push against it a bit.
 
Thanks for any help!
Risa
