I would like to recommend using Revolution.  As it protects against
fleas, ticks, mites, heartworm, hookworms, roundworms, and ear mites.
I get the adult cat doses and I extract it with a syringe and give
.075 ml / lb.  I have also used this on my rats with success.  I got
the dosage from my vet.  Just thought some of you may be interested.
Frontline stays underneath the skin where applied, Revolution is
systematic.
