See I did know about the spider wobble, I was well aware of the problem in spiders. I as being inexperienced in the morph and having one spider previously who didnt have a noticable wobble, was very surprised at this new snake being so bad. A "wobble" is one thing, but a snake thats corkscrewing and flipping its head upside down and not able to right itself looked really really bad to me.
I had no idea wobbles can get worse because of stress or just get worse as the snake gets older, etc. So I dont think I was wrong in assuming there was something wrong. Maybe I was wrong in assuming it was IBD, maybe I should have asked about neurological disorders in general I guess.
I'm sure I'm not the first person to jump to the conclusion of IBD in their snake.
I've spent quite a lot of time on the forums over the last year talking about morphs and at no time have I read that the wobble can get worse over time or get worse because of stress. If I had known that, then her arriving as cold as she did from shipping would have made sense as to why the previous owner said she had a slight wobble. Because I didnt notice her wobble being THAT bad until about 3 weeks into her quarantine. So it makes sense now.
So, again I thank everyone for your help.
Ill try lowering her hot spot.
