Update: The vet put her on the Ceftazidime (Fortaz) but overall she looked very good with the exception of pale appearance to the inside of her mouth and the presence of mucous. the tiny bubbles in the upper interior nasal cavity did correspond to an RI. My thanks go out to Skiploder for the info and assistance. I'm watching temps and (as difficult as it is) not messing with the enclosure or handling, just letting her get better. BTW, I totally misused the term "stargazing" in the earlier post, now that I've read even MORE, what I should have said was "slightly elevating her head more frequently than usual".
Additional questions: is the humid hide recommended only when I see that she is going into a shed, or keep it around all of the time?
And
Should I keep her on her feeding schedule (she has been taking a meal every 5 days) even though she is being treated for the RI?
