As it's winter, and we have the heat going, the humidity in my year old cornsnake is pretty low. I'm using aspen shavings and my waterbowl is over my under the tank heater, but the humidity is still low. I recently found out that aspen shavings dry out the cage so I was thinking of using cypress mulch to increase the humidity in the cage. However Diego (my cornsnake) loves to burrow. So will using cypress mulch bother him at all when he burrows?
