Hello everyone my name is Sean from Raleigh NC USA, I have a 3.5 year old black headed python who is starting to show symptoms of a respiratory infection as of now just some light whistles when being handled or moving too quickly and a small amount of mucus in her mouth. I've already made an appointment to be seen by an exotics vet and have thoroughly cleaned her enclosure. Her temp gradient has been kept at 80-83 on cool side going up to 93-95 hot side (rarely getting close to 100 at the hottest but whenever I see it getting that high I immediately bring it back down). I'm wondering if anyone has any experience with RI's in their black heads and if they have any idea what could cause it? It literally appeared almost over night. I did mist her enclosure a little heavily the night before I first heard her squeaks, could having too high humidity cause an infection to appear that quickly? Also could having too low humidity have caused this? I always figured they come from arid environments so I assumed too low (under 50%) would be better than too high but now I'm wondering if that could have been the cause and then the sudden bump from misting just caused it to manifest. I'm pretty anxious about this whole thing she's such a beautiful animal I hate myself for doing something causing her to get sick.
