Revolution is SUPPOSED to kill fleas within 24-48 hours, if it's not working after that call the clinic where you bought it, and let them know. Capstar works super well too, and it's quick like Suzanne says. And, if Riggs is hypersensitive to flea bites (some animals react and some could care less) then it's possible that he's just reacting to them... Remember the fleas have to bite him to die with revolution.

I love pus but I hate people.
I can say words like undifferentiated gonads now!
