As a rule in my set-up I would 1st use paper towel. Why?? Well because I spray the paper towel down with P.A.M. and same with the new snake. Even if I trust the place/breeder. Just a small precaution but could save many headaches. I keep checking to see if I see any mites on the white paper towel. Then after about 1-1/2 to 2 months of being treated then I would change up to either news paper or Aspen.

I would strongly recomend to not use the corn cob stuff. Like stated above this can leed to issues with food intake.
Hope this helps and good luck. Hope to see pics.
