Deborah -- I was hoping you notice my thread. Thank you!

She is in 10G aquarium -- should I still get a tub?
Currently on paper towels -- will aspen be better?

Yes, the logic dictates that she got to those 300+g somehow and knows how to eat. Perhaps I just panicked. She didn't have any BM while in my care, just a little pee...

I promise not to disturb her for a week and try again. How low can her weight go to be concerning? I remember you mentioned the proportions of a snake rather than the weight as the main indicator. She has rather visible back bone, but the neck is not so skinny.
