I was just curious what the other snake folks use as substrate in their tanks.

We've been using aspen for Fluffy. However, we were thinking that maybe there's something that might be a little bit more comfortable? Has anyone had experience with the dirt stuffs (Bed a beast, etc)? Paper towels wouldn't really be economical unless I shredded them(so I don't have to take out a whole piece of paper towel when I go to remove waste), right?

Thanks!
