Snake twisting around/shaky, IBD?

[Skiploder]

What do you think from the videos Skiploder?

Don't know.

Without putting hands on the animal, it's all conjecture. First guess would be some sort of neuro issue, either induced from toxicosis, some sort of trauma, a metabolic issue or perhaps a congenital in nature.

Then again, you are running the risk that it could be anything from bacterial, viral, fungal or parasitic. To be 100% sure (and in the absence of knowing the animal's history) you need to run a variety of tests.
