Anonymous, you can find a vet a vet in CA by going to
http://www.ferretcongress.org
 
There is a LOT in there so read many parts of it!
 
To find a vet in CA look FIRST in the Critical Refs in the section of
links which have vet input but are not entirely vet links.  There you
will find:
> http://www.ferretnews.org/clinic.html Vets providing multiple pieces of
> health information, with California-specific concerns
 
> http://www.ferretsanonymous.com/medical.html Medical info from vets,
> including topics not such as first aid kits, dental hygiene, and
> holiday hazards
 
Those are both CA sites and list vets.
 
A little further down that section of the International Ferret Congress
site you'll find other lists of ferret vets and that can also be
potentially useful for you.
 
Vets are permitted to treat ferrets in CA to avoid animal cruelty and
neglect, but I don't can't recall any details beyond that so the CA
sites will be able to give you particulars.
 
The International Ferret Congress Site is great place for information,
one of the sites I personally use most often.  Here are four others I
use at least weekly with daily being typical:
 
http://fhl.sonic-weasel.org  (Complete Archives of the Ferret Health
List: incredible wealth of answers to health questions)
 
http://www.smartgroups.com/groups/ferrethealth (the Ferret Health List)
 
http://miamiferret.org/fhc (Miami Ferret which has some fine vet health
write-ups among it's info)
 
http://listserv.cuny.edu/archives/ferret-search.html (I'll bet this
looks familiar!  It's the FML Archives URL which appears in every day's
FML header.  Sometimes I use this for health questions; mostly I use if
for absolutely everything else ferret, so I use it a LOT.)
 
Robin, you'll find both the reference list (scroll down) at the IFC site
in my second line above, and the several resources above to have the
answers you seek complete with details and what you are be reassured
about, so I am copying you on this.
 
Oh, another resource I use for a few additional things which aren't in
the above resources or in the wonderful links they mention (so maybe use
about every week or two) is http://www.fothferrets.com/ferretinfo.html.
That one should be useful for you, too, I suspect.
