It did NOT work

The Frontline seems to work best for out cat. We live in Florida and use it all year. The cat spends about 6-8 hours outside every day and flea treatment is very important.

Disappointed in its strength. Have seen some lessening of fleas on my cats, but certainly hasn't eradicated them. Has helped some, but not as much as i hoped.

Bad shipping. I got the package four days after they said it was delivered and it had been opened and box was tore up. Item might be good but product I got was in bad shape.

It did not work. I have several cats. I used a couple vials on some of the cats and I haven't seen any dead fleas. Only a bunch of live ones and more flea dirt than ever. This is not working. Now I have to find something else. Not happy.

useless on my dogs and cats, cant get rid of the fleas, even in the middle of winter. there arent any in my house but they are on all my cats and dogs and frontline each month does nothing. did they make this weaker in order to make more money?

[This review was collected as part of a promotion.] the prices are higher than at other websites, but I needed it right away, so I guess I paid for that.

The product said Frontline for Cats on the outside labels but inside was medicine for dogs, which is toxic to cats. I had to take my cat to the vet after accidentally using the product and her developing a toxic reaction.

This product did not work for my cats. Gave 2nd dose after 15 days because still seeing adult fleas. I have used this in the past and it worked great but not i have to go spend more money on something else.

Frontline plus has had problems with counterfeit products. This box was opened and had evidence of being counterfeit, missing instructions and did not look right. Should be sealed. I will not trust Walmart for this product.
