Time to order flea control for my cats. They are both indoor cats, but my dog brings fleas in from the outside. I've had great success with Advantix for my dog, much better than Frontline Plus. I was wondering about Advantage for Cats vs. Frontline for Cats. Any opinions? If you use something different, better, please post! Thanks in advance! P.S. - Yes, I know there is a difference between Advantix for dogs and Advantage for Cats.
