One of the best products to keep fleas off your dog or cat. I hate fleas!

Pros: Very effective and reliable.

Cons: A bit costly.

I use Advantage on my cats, and really like the way it works. Every month I have to re-apply it , but its no big deal. I have yet to find a flea on them and knowing that is a good thing. It can be a tad bit greasy, but the day after its been applied the greasy spot is always gone. Love the product, everyone should use it!

Pros: Works fast, effective, and is easy to apply.

Cons: Some what greasy.

I use this brand the most. I have 7 cats but only 1 goes outside. She was an outdoor cat when she appeared at my door and she still likes to be outside when it is nice. So to protect everyone from fleas we use Advantage. It can get pretty expensive when you have to buy for 7 but it's worth it. It seems to last a long time. I ususally just apply 2 times in the summer and once iin the fall and that's it. And I've never had a flea infestation.

Pros: Lasts a long itme

Cons: expensive for 7 cats

My family loves this product. It was gentle enough to use on our 18 year old cat who had a major flea problem, but strong enough to handle the problem. We haven't had any problems with it. However I did know one person who had two cats who bathed each other and they tended to lick it off each other and get sick. Our cats don't do that so it wasn't a problem but if your cats are close and bathe each other, be a little careful.

Pros: Easy to apply, works for a long time

Cons: None

This is the only flea treatment I will use. Love it.

Pros: easy to use, reasonable price, works well

Cons: none
