Excellent for killing fleas, but no effect on ticks or other parasites. Very safe for cats.

Pros: kills fleas

Cons: no effect on ticks

Great product - it does last longer than others. Closer to the four weeks advertised.

Pros: effective

Cons: none

Works wonderfully well on my cats. I've one that has skin allergies to fleas, and one application of this lasts nearly a month with almost immediate results.

Besides being expensive (about $10 per application), my only big problem with this is I have to apply it then not pet my cat for nearly 24 hours - it's not good for humans to have contact with the chemicals. But after that, it's all good and gets rid of the fleas extremely well.

Pros: Works VERY Well

Cons: Bad for Humans; expensive

The last time I had my cat to the vet he changed her old flea med to this. It was very effective.

Pros: It kills those little buggers

Cons: none

This is how i keep my cats flea free!!

Pros: gets rid of fleas

Cons: none
