I've been reading around a lot on humidity. High humidity is an issue because it causes bacterial growth, bad sheds, RSI and/or mouth rot, but would low humidity (let's say 45%) cause even more problems, or even less problems? Now my snake's vivarium normally stays around a base of 45-50% (normally 50%) and an overall temperature of around 80-85 Fahrenheit.
Me being the paranoid person I am always worry about the humidity and my snake's chances of getting ill with those gradients (45-50%). I just need clarification so my worries can be at rest.
Also, sometimes I notice tiny amounts of bubbles in his mouth (sometimes it's there and sometimes it's not), is this just saliva?
