One thing I have noticed is she yawns quite a bit. Not so much today, but yesterday when I brought her home, she probably yawned 6-8 times in a couple hours.

I'm sure she had a long day, since she just got shipped into the store that morning, was put into a new home, held by many different people, purchased by me, then put into another home. I guess I would be pretty tired too

I've just never seen this on another snake. I never say my brothers boa yawn once for the 9 months I watched her.
