First, I did not think that frontline should be used on such a young kitty - but I could be very, very wrong - so be sure to check. But having said that it is great stuff - hopefully once you have coped with this you will eliminate it completely with future applications.

we got a kitten 15 years ago from a farm - it was the height of summer and we just could not get on top of the problem - YOU'LL ALL SCREAM AT ME NOW as a last resort we bathed him in warm water and I do not think we have ever seen a flea since (but we do use frontline every 3 month). That kitten by the way was just a month old when we got him - he's fiftenn now and never (touch wood) had a days illenss other then that he was run over once and not related has had to have most of his teeth removed.
