For my first snake, I adopted a 65-70cm unsexed BP who had been found injured (in north Alabama) and treated for an abscess. She has been a good eater for me so far, eating a jumbo mouse every 10-14 days.
She appears to be a normal morph, but expresses a head tremor. Different than a spider wobble, from what I can tell from youtube videos. I often catch her shaking her head rapidly (back and forth, two or three times a second). She shakes it laterally, about 3cm. It appears to be rooted at the base of the neck.
Furthermore, she has begun eschewing the hide in her cage (in the hot side) for an elevated, fake tree branch on the cool side of the cage. As I type this, she is actually curled up 20cm+ off the ground - as if she wanted to be an emerald tree boa when she grows up!
Ambient temperature in my house has been 84 degrees during the day (it is Alabama, after all), and as low as 70 at night.
One side of her gut makes me think 'het for spider', but I know spider is dominant. Im fairly sure that I am just imagining things on that front, but I dont know what to look for regarding morphs. I have gone through NextWorldExotic's amazingly helpful guide (just what I was looking for!) but I have a neurological condition that can make abstract pattern recognition difficult.
