At Cornell, we used injectable (ketamine) and gas (isoflourane) for
ferrets.  We did find an increased incidence of seizures with ketamine,
though I'm not sure about the other injectables.  I prefer isoflourane,
as the safest of all options.
    I'd love to hear from the other vets on this one, cause as soon as the
law passes, I plan to start a ferret practice!!  i miss the little guys!
