My concern would be that I use soap & shampoo when I shower, but it's not meant for snakes. With the water running, I can't say I'd feel un-clean for
touching the snake but no snake should be exposed to our bathing products, & I wouldn't feel clean with just water. The snake didn't really appear to be
enjoying that shower either...it's just a silly thing to do. I don't know anything about the guy in video, but maybe he's trying to show ppl how much he
trusts this snake?
