Soaking alllll the time-- is this bad?

[FollowTheSun]

I'd lower the heat mat to about 85*...she's an "albino" black rat snake, & while they like humidity, too much can cause issues too & they're adaptable anyway.
(what % of the floor does the heat mat occupy? is it at one end or in the middle?) A better way to offer humidity is a humid hide...use a large enough plastic
food container (lid on) & cut (or melt) a doorway in the top, fill with damp (fully soaked & drained sphagnum moss) & refresh periodically to keep it damp.

Yes, your heater blowing on the cage sounds like a REAL issue. Always have to be sure of cage placement with regard to heat, A/C vents and windows that sun
can stream in thru- avoid all those! All cages should be in a stable area, well away from all that & away from doors that open to the outside also (for drafts).

Snakes "burrow" when their hides are too tall & too open...easy fix: crumple a paper towel or two & stuff them inside! You'll find your snake in there, happy.
Or you could probably give her a Christmas stocking...(an old un-matched sock works too)

And rather than misting, a larger water bowl will add humidity, especially if it's near the UTH.

Thank you! I'm learning a lot here! I will set the heat mat to 85. It is a small mat about 8x8 and pretty much only occupies only the area under her warm hide. She has a large enclosure and the mat is on the far end of one side. The Christmas stocking is a great idea!! I'll work on making a cool humid hide for her.

I was mostly using those plant jars to keep the humidity up rather than misting (in our dry climate misting lasts like an hour). I have put in a large but shallow dish instead of the jars for now.

I do think the main problem is the furnace blasting her, but I have learned a lot of other useful things in trying to troubleshoot that. Thanks again everyone! :-)
