This product worked well for the first few years but doesn't seem as effective anymore. Buyin the 3 pack is less expensive so if you are using this product this makes sense.

Pros: cheaper buying 3 pack

Cons: not as effective

I've used this product for many years on our cats and find it is very effective. The time span of effectiveness seems longer on cats than on dogs.

Pros: Works very well

Cons: Cats hate it applied--smell I suppose

I used to use this, but I can't afford to buy it. It worked great though.

Pros: Great product

Cons: too expensive

I use this on the cats all the time. Even in the winter. I have yet to see a flea on any of them. It really works,and it works great.

Pros: Works great

Cons: Expensive

Have used this on my cats. I works on fleas. I did change to Frontline Plus but this regular Frontline is a little cheaper.

Pros: It works

Cons: None
