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. [Posted in FML issue 4538]
