Hi! I don't post on here often, but I have a rescue spider.
I've noticed that her wobble generally worsens when she's stressed or had too much handling for one day. I really wish they weren't bred and I'm sorry the breeder didn't inform you of the neuro issue these snakes have. It can be really frightening and heartbreaking to see. I hope you listen to advice and don't breed these animals.
The only other advice I can give is that you have to be very careful with feeding. I tend to open both doors, lift the hide she's under up and get it out of the way, and hold the rat a little higher so she doesn't hit anything with her face.
