Advantage for cats or dogs is the same product that is just prepackaged in the correct size for each species. I believe Frontline is the same way. I always purchase the Frontline spray as it has a better shelf life than a vial you open and need to use or discard the leftovers. The one you need to remember NOT to use is Advantix. This is likely what was used on your cat. An easy way to remember is NIX the AdvanTIX. (Nix sort of means 'get rid of'' or 'put a stop to'. No dictionary handy!)
