Protects our cat well.

Two of my cats were having flea-related skin issues. The vet recommended that I switch from the high quality brand I was using to another high quality brand to see if that would produce better results. He recommended Frontline. From the first application, the issues were resolved. This experience showed me that I needed to match my desire for quality with the compatibility of the animal.
