I bought the 3 pack at Petco so I know it is the authentic version of Frontline.It was around $80!
I only bought it because I forgot to order the revolution online and it was time for the treatment (every 30 days). We have more fleas than ever and I am seriously bit up. My cat is miserable and now we can't do any more treatments until August 21 (30 days) for risk of overdosing the cat with more meds. I am going to give him capstar every day until Aug.
21, just to keep him comfortable. I have already ordered the revolution and we will go back on that. This has been a very expensive mistake.
When my cat is on revolution we have no fleas whatsoever on him, on me or in the house.SHAME ON MERIAL.
