I was reading a post in the "Giant Snakes" forum, and I came across an article that said something along the lines of: snakes obtaining their necessary vitamin D by being outside in the sun. Now, I am just asking around to see if this is true. For me, I have never taken my BP outside, but I read lots of posts of people who take their BP to a park for a quiet "walk". But what I'm just asking is that if it's true. Do BP's really need vitamin D from being outside in the sun, or do they get all their essential nutrients from what they eat?
