I have noticed last night and some this morning that once she gets done using the bathroom she wipes her butt on the floor (Ive see dogs do this..but never cats)...is she just trying to get the poop off (still has diarrhea) or is it something else?
If she does have worms- will the Revolution medicine that she got Wed take care of it?
The butt scooting is normally either because of worms or anal sac issues. Two things....Revolution doesn't treat tapeworm, which a lot of kittens and cats have because they can get that from ingesting fleas while grooming. It only takes one flea, if it's the right flea. You might talk to the vet about that. I have had cats that scoot because of tapeworms.
The other thing is that a good firm/normal stool should naturally express the anal sacs in cats. Anal sac issues aren't nearly as common in cats as they are dogs, but it does happen. A short bout with soft/runny stools is enough to aggravate that. When they scoot, they are trying to express the glands.
Either way, it's an itchy butt and not normal - might want to mention it to the vet.
