trying to get comfortable or something else?

I fed my snake last night (2nd time feeding) and after he's done he goes right bank in his hide. Last night however He got a drink then started to switch from hide to hide. Was he trying to find the prefect spot to lay or was he searching for more food? Last time I weight him he was 100 grams which was on the 6th when I got him. This was his 2nd rat fuzzy with me and I haven't handled him yet. Should I wait till he digest his meal and take him out to weigh him? Also could he be in between sizes?

Definitely wait a couple days to weigh him. I'd actually wait until right before the next time you feed him, after he poops and he's empty from this meal. I know my boy can drop 10 grams when he poops, and he only weighs 140g, so I wouldn't weigh him when he's still got that food inside him. Then you can go from there on food size.
