I'm not sure if I should take my kitten to the vet or not. She has tiny black dots all around one nipple and a little on it and on two more the dots are fainter and smaller but not bumpy. When I first found her she did have flea dirt and was treated and I thought that was possibly it. She's been flea free since (last visit was 2 weeks ago) but the dotting, almost like a spray of them, is still there and it seems they're actually on the skin. She doesn't appreciate my prodding around there so I can't really get close enough for anything more than to see. She did have severe pyrometra and got spayed right away, I don't think one has to do with the other but I thought since it was her nipple area... I just can't find anything on this, it can't be birthmarks can it?
