I was curious.. I know we all have our own prefrences but what do you think the snake would prefer us to use?

I have been using paper towels & just decided to try aspen on one of my bp's. She doesn't seem to like aspen at all! I put it in earlier & she is just hanging out on top of her hide. Poor girl I think I am going to have to put paper towels back in for her so she can rest.
