Yes, they typically stay in their hides when going into a shed. Considering that the last time she was out she saw the vet, then got fed, I'd hide if I was her too.
You can verify this if it will make you feel better: use a penlight (small flashlight) in darkened room, lift the hide & shine the beam across the curve of her eye...
if she's in shed, her eye will appear as milky (more or less milky, depending on how far along in shed cycle she is).
You know, of course, that the reason so many of us have multiple snakes is so we have pets to see & interact with when some are laying low?They've got us!
Just make sure her humidity stays up during her shed cycle. It can take a while & the exact time varies: but some days going "blue", then some more days going
"clear" (fluid secreted by snake's body to facilitate the process makes the old outer skin appear to be the "new" skin, & the eyes are clear, only you won't find the
shed), & then finally the actual shed process. Snakes teach us patience...![]()
