Totally confused here. Your original post says you let humidity drop to 10-15%. By using the word letting I assumed you were in complete control of the humidity in your snakes cage. Your latest post states 10 to 15% is the outdoor humidity with 30 to 40% humidity inside with a spritz of repticbips thrown in now to possibly have 50% humidity inside your cage. Both of my arms will go verticaly straight up at the conclusion of this post.....I give up. Are we over estimating the importance of humidity? I'm not sure if that should be the question. The question should be do you really understand what you are posting? If so that is your right and I'm cool with that. I will just make sure never draft a speech for me or let you baby sit any of my snakes. Ever thought about a pet cactus?
