Is this a counterfeit product?
Frontline has worked great for us in the past, but this product does not seem to be working after 2 months. We have a terrible flea infestation. I called Frontline and they will not guarantee their product if purchased from Amazon. Is this the real thing or counterfeit? I am very disappointed.

great product
I use this over the others because it also handles ticks. We used to have fleas bouncing around our floor during the summer if I didn't vacuum and comb the cats twice a day. Before Frontline, we made a game out of squishing fleas. It kept us sane.

Good product
Used this on two feral (stray) cats who have adopted us. They came to us with fleas and one seems to be allergic, as well. Within 24 hrs of using this product, they got relief. The only problem is that it only lasted about 3 weeks. In fairness, our yard is full of squirrels and they are notorious for having flea infestations, so I'm sure that's why it didn't work any longer. I've used this on my indoor cats with much more product longevity. I would buy this again.

Frontline
The vendor did an excellent job communicating receipt of order and the shipping of this item was right on target as the vendor stated. I will purchase from them again. As for the product, it's for my cat, and perhaps she thinks it's pretty good because she doesn't have fleas!

frontline plus for cats
This is the same product that is available through a vet's office, without the additional expense. The product does exactly what it promises, kills ticks, fleas and their eggs. Frontline Plus Cat, 3 Month
