Anyone used Frontline Plus for Dogs on your cat?

If the dose concentration (mg/cc, etc.) is the same for both formulas, then you can adjust the dosage (in cc) for weight. I've done this with Advantage, using a 1 cc syringe (no needle) because I know the concentration for all tube sizes is the same. I don't know about Frontline.

As I recall, FL+ for cats is stronger of methoprene than is the dog version, so it's safe to split doses. PDFs take forever to open with dialup, so I'm not double checking that info. You can open the PDFs at the bottom of http://frontline.us.merial.com/produ...cts_flplus.asp to check for yourself.

You are right, the cat version is a bit stronger than the dog version so there shouldn't be a problem. It just may not kill the fleas as long.

Technically, S-Methoprene doesn't kill fleas; it's an IGR (insect growth regulator). I doubt very seriously you'll see much, if any, difference with the lesser strength.
