ty for the responses.
-I'll black out the tank when I get home. I'll also add more to the tank to be sure of security.
-He is currently in a corner of the living room. The only traffic he sees is the dog moving from couch to couch and me sitting on the comp when I get home from work.
-Aspen is about 4+ inches deep. He hasn't been borrowing which I find odd for a burrowing snake and he's been laying out of his hides.
-I'm gonna call the vet today and make an appointment. I'd rather not toy around with him being sick.
For clarity if you did not see it in my post:
"...I held him this morning for the first time since bringing him home..." I pulled him out to weigh him so I could track if he was losing weight while not eating and he seemed odd so I examined his behavor of him being in my hands and put him right back. He was out for about 5-10 minutes. It was a comparison to how he was the previous time I handled him. Otherwise he would not have been pulled out. I know better than to have him out before he's eaten for me unless there is an issue.
