The ferret could have blackheads.  I've heard people use Sti-dex on them,
but I don't know how often this is done.  Thought if a ferret has Ear
Mites, it starts in the ears and then they work down to the tail.  If I'm
wrong, please correct me.  They get on the tail from the ears because of
how they lay and their face goes near the tail.
