Jessica asked about sneezing ferrets.  Since I'm something of an expert
in the field of ferret sneeze-ology, I thought I'd respond.
 
Jessica, ferrets sneeze.  It's a fact of life.  They eat, they poop, they
war-dance... and they sneeze.  What you've described is fairly typical
ferret sneezing -- a couple each day.
 
Remember that ferret legs are only a couple of inches long -- they're down
there in dust that most critters with longer legs don't really notice, and
more than that, they stick their faces into places critters without the
obsessive curiosity of a ferret would never look.
 
Now, if your girls start sneezing a lot -- say, twenty or thirty times a
day, on an ongoing basis -- then you have something to worry about, and
should talk to your vet.
