I use the kitten dose of Revolution on my ferret.  She as adrenal disease
and the only "reaction" she has had to the Revolution is a slight reddness
to her skin where I have applied it.  Advantage is has also been dispensed
for ferrets at my hospital.  I personally chose Revolution because it also
protects against heartworm disease.  Living in TX I have mosquitos in my
apt. every now and then.
