the only advice i have when using this product in a multi-animal household either separate the animals after the frontline is applied until it dries or apply under their collars so they can't lick it off each other.

Pros: very effective product

Cons: may take a few monthly applications

The frontline drops just are not effective on our cats anymore. As of 2 years ago they seemed to work fine. Starting 2 years ago they did nothing to kill the fleas on our cats or keep them from getting new fleas.

Pros: Did not harm our cats

Cons: This product did nothing to kill the fleas on our cats.

We used this until oru vet recommended K9 so we switched. We like them both, but, this one does not have mosquito protection, so we use the other one more since our peanut likes to go outside.

Pros: works well, not sure abotu mosquitos though

Cons: no mosquitos

Its not as effective as another product i use, but it is a little cheaper and i trust it not to hurt the cat.

Pros: safe to use, works fairly well

Cons: none

I have used this and it does a fair job, I do not beieve it does as good as it used to. Its real hard to buy this for all the cats at a shelter. I like another product better.

Pros: somewhat effective,

Cons: expensive
