Although I have not heard or used this product, it does say it is cork bark which is safe for enclosures that house snakes. With that said, if you are looking to do things absolutely right, I would think about using aspen, newspaper, or paper towels instead. If you are set on using cork bark, just make sure that it doesn’t compact easily and you should be alright. If it does compact easily when humidity rises or when it gets wet then I would definitely suggest finding a new substrate like one of the ones I mentioned previously.
