I recently adopted a King snake from a friend. Since I have had him he has been making this noise like a sign. It doesn't seem quite like a respiratory infection more like he has dust in his nose which makes sense because he only does it when he is rooting around with his nose in his bedding. A question for people who know more than I do, is something like that possible or is it something I should be worried about? If it is just because he is kicking up dust from his bedding is there something better than aspen which is what I have been using? I would hate to have to change it so something like newspaper because he really enjoys his rooting.

Thank you for your help!
