It's nothing serious, this is more of a curious inquiry. Since day one, Pretzel my rosy boa would sometimes look at me upside down instead of turning around like the other snakes do. Also, when she is flipped over, she may stay that way for a period of time too. This doesn't bother her, her appetite is great (She tried to eat my hand), and is growing like a weed. It reminds of the spider wobble in ball pythons, she doesn't seem to try to hard to 'right' herself. She also has a slight wobble. This behavior usually shows when she is excited for food. Most of the time, she doesn't wobble and looks at me correctly. Do rosy's have this kind of defect too? Her locality appear to be somewhat rare, I wonder if some inbreeding may have occurred too.

Not knowing what this is, I am going to give up my plan on breeding her even if she grows out of it.

Her temps are at 88 hot spot, 75-77 cold temp, and heat mat is on a herpstat. I think she is born like this?
