Once in a while my girl Bermuda seems to get conjested.  She'll cough and
it sounds very phlegmy.  I will give her hairball medicine and it seems
to make it go away.  My question is:
 
Is that what it sounds like when a ferret has a hairball?  It's not a
hacking cough.  Could a ferret get a cold every other month?  My other 3
(Cyn, Bear & Magenta) never show any signs and they haven't been given
hairball medicine.  Any ideas?
