Hi,

Is she due to shed? Sometimes that can cause them to make noises while breathing.

I would try and hold her head close to your ear and listen to her breathing for a little while when she is not stressed or breathing heavily. You could also try and have a look inside her mouth to see if there is any sign of excess bubbly mucus.

It might help narrow things down if you could give us an idea of the temperatures insode your setup and how and where you are measuring them.

Have you seen her rubbing her mouth on cage furniture lately or anything - or noticed slimy stuff in the waterbowl?
