I have been using Revolution for about 6 mos.  My vet went to a conference
and says it is one of the best and safest products available.  I use it on
my Doberman (she's a ferret wannabe).  The vet said to use 1 drop from the
tube on each of the 4 ferts.  I use it on the 2 cats also... It apparently
works so well that even if you only get on half the reccomended dose it
still works.  We have not had any reactions.  It is so much easier to use
(only 1 would take the Hartgard, and liquid invectrimcin was absolute
torture).  Hope this helps!
