Ok, so I now there are tons of threads about URI already, but here is another one. I know that some reptiles open their mouth when they are basking, but do snakes? Lately, Jasmine, one of my colombian boas, has been keeping her mouth open, and last night she started opening her mouth to breath. I could hear her breathing. I know that this could be a sign of an URI. I haven't seen any bubbles. I know some about URIs, but not everything, so could someone please tell me the usual symptons? Also, I saw that she has mites last night as well. I have no idea how she got them, but I will take care of them. My question about mites is can semi-aquatic turtles get mites? My turtle's tank is under Jasmine's tank, and I'm worried about them. I really hope that she doesn't have an URI, because if she does, then most likely 6 of my other snakes will get one too.
