Why I Chose Advantage II for My Cat
I was looking for a flea treatment that was effective, easy to apply, and safe for my cat. Advantage II caught my attention because it promises to kill fleas at all life stages — eggs, larvae, and adults — which is important to stop the flea cycle.

One thing I appreciated was how simple the application was. The packaging comes with pre-measured tubes, and I just had to part my cat’s fur at the base of her neck and apply the solution directly to the skin. It dried quickly and didn’t leave a greasy residue, which made me feel comfortable letting her groom herself afterward.
Safety and Side Effects
