Oscar has a severe flea allergy - He had hives for DAYS maybe 1 yr ago or so, I kept up with Benedryl, and finally when he was STILL trying to scratch his face + body on the pavement and carpets 24 hrs later, I started him on Steroids. 24 hrs after THAT(and still maintaining a dose of steroids), we noticed him rubbing himself, just for a split second, AGAIN; I checked him closely, and even with the anti-inflammatory properties of the steroids, he had mild hives again. As I was checking him over, I found ONE flea. I only ever saw the one.
Typically, I would think, "If you see one..." the standard issue "there are 100 more", but I have one pet, and I live in a free standing structure, and the reaction went away after a day or two more of steroids and Advantage. We haven't had an issue since. So I suspect, rather then my house being flea ridden, it was just one flea.
Anyway, moral of the story, he may be having some kind of reaction to previous flea bites. I'd try flea combing him and see if you get any live ones. Other then that, he may need a bath to wash away any flea dirt or saliva on his skin that is irritating him.
I'm not really familiar with Revolution, but the impression I got is that it should be affective within 24 hrs. If it isn't working, the place you got it may be able to help you with that.
I can only please one person per day. Today is not your day, tomorrow doesn't look good either.
