No the mites are microscopic, if you use Revolution on your kitties and they have the mites it will kill them, if it does not clear up then it will be kitty dandruff for sure.

I just queried this about my own kitties on their last visit, obviously the vet cannot tell just by looking either, she recommended using Revolution or Advantage Multi, I intend to next time, so we shall see if the kitty dandruff clears or not, usually they groom a lot if they have mites she told me., hope that helps you and Kim.
