actually i just put her on the scale tonight and she was 152.after a pooh im guessing 135.she can take a medium but id rather give her 2 small(since she is itty bitty)a large is outta question.i have a 300 gram male that had a stuggle with a large mouse.this thing was massive!i was lookin for rat hoppers and the lady came out with a bag and i trusted her.bad mistake!it took the snake at least an hour to take it down.i felt so bad cuz i knew it was big but i fed anyways.it struggled the whole time and after it was done it took 5 days to come out of its hide that i had to modify with a dremel tool.
