Thamnophis on speed

[guidofatherof5]

I don't give her any vitamins because I feed her pinkies from time to time. I have a theory that the occasional mice will do it. But now I will consider it! Thanks for the link.

You don't believe it can have anything to do with her pregnancy? Not that I close my eyes for the possibility of b1 deferiency but I really do find it strange when it disappears that fast again

I can't say I've ever seen that type of behavior in a gravid snake.
Could you have a mite problem?
If a snake has them their behavior can look pretty weird as the scratch themselves. Just a suggestion
