I went to check on my 3/4" b smithi (who is in pre molt) and she freaked out and ran in circles and tried ro climb up the walls. I know she's not stressed. I have her in a quiet room and her enclosure has a clear lid so I can just look in at her. What could this mean? Also she fell when she tried to climb up (she's not a good climber). It wasn't a very far fall, not even 1/3 her legspan, but i'm a bit worried. Should I be?
