Aww, Gaby is a true pro burrower, lol!!! She does look so sweet trying to get her extra quota of cuddles from you, too.
I had to laugh that she denied herself the third mealworm and sunflower seeds just so she wouldn't feel obligated to be on her back, lol. She sure has strong determination, or maybe she realizes that you will give her those that she is missing in no time just for being her cute, silly self.
