So i just took my snake out and it seems there is a slight whistle. She isnt breathing open mouthed or anything. She did seem a little stressed out when i took her out. I noticed today that her color is changing and its time for a shed. im thinkin is this part of shedding or being stressed? or does she have a respitory infection

Temps of tank
hot side- 90
Cool side- 75-80

Humidity: 50%- 60%

Substrate: Aspen

Heating: UTH and bulbs... three thermometers in tank one a digital with probe, no thermostat yet.. tmr is the day.

If its respitory infection i was told to turn up the heat so im going to see how that goes.

What do u guys think, should i go to a Vet ASAP or wait a day or two and see if it stops.

She doesnt whistle constantly, its hard to hear and sometimes u have to wait a while to hear it again. She is starting to shed i heard that could be it. Shes in the early stages of Shedding.
