To Gerry Roston concerning flea products  (Reposted, per your request)
 
The three largest groups of flea products are the organophosphates, the
carbamates, and the pyrethrins.  Of the three, pyrethrins is the ONLY one that I
recommend for use on ferrets.  You can also use it on kittens or puppies.
Pyrethrins is a natural product of chyrsanthemums, although now a lot of
pyrethrin compounds are synthesized in laboratories.  However, they are all
safe, and I have not seen any problems with their use in ferrets.
 
Organophosphates, and carbamates on the other hand, can be toxic if
applied in high doses.  The signs of organophosphate toxicity is the
paralysis-like syndrome that you described above, in addition to dilated pupils,
drooling, loud stomach rumbles, etc.  Severely intoxicated animals may stop
breathing, or may have long-lasting neurologic effects.  Organophosphates, in
highly potent concentrations, are the leading component of nerve gas.  WQhile
adult dogs and cats may tolerate this material externally for the killing of
fleas, smaller animals such as ferrets are highly susceptible to overdosage.
 
If it doesn't say pyrethrin on the label, put it back.  For best
results, call your vet for instructions prior to using any flea product on your
ferret.
