[Cassiopeia]

is that on the hot side?

Yes thats on the hot side however right now it's 75.

when she yawns does she keep her mouth open for a long period of time or is it quickly shut?

She shuts it rather quickly. I've never seen her hold it open.

1. Check her mouth/nose for mucus
2. Move the side of her bottom lip down with your thumb and check for small bubbles. Should be a nice pink color with no bubbles.
3. Take her out and handle her for 10-15 min then turn off anything that makes sounds and while holding her up close to your ear listen for wheezing/popping. You should not be able to hear breath.
4. Check the sides of her enclosure for smudge marks. if they are producing mucus as the result of an RI you will sometimes find evidence of that rubbed off on the walls of their enclosure.

I haven't seen any mucus around and I thought she may have been trying to get mucus out of her nose by bumping her nose on me a little forcefully but I didn't feel any on me. She doesn't make any noises and there are are no smudge marks on the edge of the enclosure.

is your heat pad regulated?
With those temperatures and a dry feeling belly you could possible have created a RI and belly burn?

You misread that part, her tummy is smooth but she feels a bit dry but she is due for a shed (no signs of one though and she hasn't shed with me yet and I got her in early September when she just finished a shed). And yes it's regulated and set to 90 with a thermostat.

Also I know sometimes the tongue flicking can be from stress or off husbandry so I hope she's fine once we get her in a warmer enclosure.
