Hey,i just wanted to give a heads up on this bedding/substrate called care fresh. It is amazing! it holds humidity well and is easy to clean and none toxic.Care fresh is just a bit on the pricey side compared to aspen. I know some people get torn between using aspen,paper towel or wood type substrates because of all there cons like with the wood type substrates like repti bark or cypress it hold humidity well but can easily attract mites and with aspen it can sometime get a bit dusty or not hold humidity to well. With care fresh it hold humidity ad does not attract mites and is really easy to clean. Just do not feed your snake in the enclosure with it.Care fresh is also environment friendly ! here is a pic of it
