I have three rats (1 black, 2 b&w). I've noticed small red/orange/brown flakes/specks on the white ones' fur (I'm sure they're on the black as well, but I can't see them). You can't really see their color but you can see their size in the photo. They don't have a lot of them and I only see them on the fur, not so much the skin. They're also on the ends of the fur, not so much the root. I had them on a mix of Yesterday's News and Carefresh (which I froze). Right now, I have thrown out all their old bedding and given everything in their cage a clean. All of their fabric hammocks are out of the cage and they only have Yesterday's News, no Carefresh. They don't seem to be itching, so I'm not sure if these are mites. I was thinking of giving them a couple days to see if things change then taking them to the vet. Could these be mites? What can I do to clean their hammocks in case they are mites (I was thinking just washing and freezing them)? Is going to the vet necessary or can I just get them meds myself? Thanks!
