In reading your post I feel bad for the snake. That environment can't be good for it. Snakes are not the kind of animal that you parade around with. They need to be in the warmth and safety of their cages except for the occassional handling in the privacy of your own home.
I sincerely hope you reconsider using this snake in your dance routine. Just not fair to the animal.
What I fear most is that your snake will act out in one of your performances and then once again "snakes" get a bad rap from the public as being dangerous. Please rethink this.
Thank you
