I ordered Frontline Plus for cats. The medicine that was delivered was in a different package than what you buy at the pet store. I didn't think a whole lot of it, just assumed it was different packaging since it was delivered from Canada. The Frontline DOES NOT WORK! It doesn't do ANYTHING to the fleas. There was no reduction in fleas, whatsoever. Do not buy from this website. They are crooks with bogus, counterfeit products.
