I'd keep an eye on her and bump her temps a bit like you mentioned. If you can get a shot of the inside of her mouth that may help shed some light, but I would personally see how the symptoms are over the next week or so and go from there (vet visit asap if you see her decline, of course). RI's when caught early are (usually) easier to kick then when more advanced, so if she does have one at least you noticed it early on. Always have a culture done with RI's: after dealing with a snake that was resistant to Baytril I can't say enough how I wish I would have gotten a culture from the get go.
