Ive noticed within the last week or so Ruby has been climbing up on her hammock and trying to go to sleep before her lights go out at night. They are on a timer and go off at 9pm and 9:15 pm and that has not changed. She has also not been basking as much, sitting in her hammock a lot of the day. She is eating and pooping fine. Any thoughts why shes wanting to go to sleep early ?
