i agree with ballpythonluvr. It would be an absolute nightmare to clean but i dont see an issue with it bein used given u have proper heating set up. i think people freak out way too much over simple stuff. these snakes have lived for thousands of years without us telling them what they can and cant slither on. besides being a pain to clean i see no reason why it couldnt be used. I for one wont just becouse im not cleaning all those rocks lol.
