It is good stuff. I don't like putting it on my cats cause that is just me.

Pros: works great

Cons: how you but it on

I have used this for my cats and found it to be very effective. My cats do not go outside, so I sometimes just do a flea treatment. The important thing is to get your remedy from your vet - they work the best!

Pros: protects against fleas

Cons: is expensive if you have many pets

Frontline works wonders on fleas on my cats. It is easy to apply to the back of their necks, lasts for months and really keeps the fleas off all over their bodies. Very effective and no side effects with this product. I am always surprised at how much it costs, but it is worth it for my babies.

Pros: Easy to apply and stays on

Cons: cost

This product works, it kills the fleas that bite, but does not repell. So when petting our cat, I would still find fleas, but they did not bite, and would shortly be gone. But if you have outside inside cats, this is not a good product, the animal will still bring flea's in the house.

Pros: kills the biting flea

Cons: does not repell

I used frontline for awhile, but i was still finding fleas! It did get rid of the majority of them. I switched to advantage and all my flea problems seem to have gone away.

Pros: better than nothing

Cons: not as good as advantage
