After I ordered Frontline Plus for cats I did a bit more research and I have no doubt that what came in the mail is counterfeit and would hurt or kill my pet. A closer look at all the positive feedback and its pretty obvious that's its all padded. All the positive feedbacks are never product specific and they are all just praises of the site. THINK ABOUT IT! Do not buy from this company! It is a fake and a fraud! You hear about counterfeit product... well this is what people are talking about.
