Substrate for corn

[wilomn]

I currently use paper towels as substrate for all my snakes. It seems my new corn prefers to burrow under it. I believe she was kept on aspen at her previous home. Should I switch her back? I already have it on hand, as I use it for my rat's bedding. It just doesn't seem to me that it would be very comfortable against a snake's skin. Are we sure that it doesn't have the same harmful effects as pine/cedar?

Any input is appreciated.

Are we sure pine has harmful effects?

She has a tough skin, use what you like, paper or aspen.
