Okay, thank you for your answers! I checked her today, her color is almost back to normal. It's not pink but it is a little off color and seems dry. ambient air temperatures are around mid to upper 70's. She went into the warm hide because I removed her cool hide during feeding because otherwise she usually doesn't notice the rat. when I replaced her cool hide after she swallowed the ride she had already gone into her warm hide.
My thermoSTAT is set to keep the pad at 90; it has a temperature probe on the thermostat for sensing the temp and heating and cooling as needed. The probe got shuffled somehow so it gave the thermostat an inappropriate reading, making it up the temperature in am attempt to meet the required 90.

I have since taped the probe down to the hot spot on the glass and put substrate back over it to prevent future mishaps. Is there anything else I should do? I'm using a Hydrofarm hydrometer as a thermostat . I saw several snake owners recommend it as an affordable temp control when I first switched from heat lamp.to heat pad.
