Aspen Vs Shredded Paper?

[maroongrad]

I had my snake on what I thought was the aspen repti-bark, but it had a strong scent to it and turned out to be FIR! I figured that, for an animal that is always "tasting" the air, it had to be an unpleasant experience and I worried about health issues. It smelled way too much like cedar to me and I wasn't about to keep her on it.

So, I switched her over to white, shredded paper within a couple days. She seems fine with it, loves to burrow in it (which she wouldn't do with the bark) and it's really easy to spot the dirty bits and clean them up. Well, easy except for the biting.

Is there an issue with snakes getting impactions from the shredded paper? If I feed her outside of her cage, would that prevent issues? I'm trying to keep her comfortable and healthy. I also really like the paper because I can get it damp and it releases humidity slowly until it dries. At which point, I flick a bit more water on it.

Can I keep her on the paper, or should I move her to the aspen repti-bark?? First snake here other than a few wild-caught ones we kept a week or so to show the students, and we're trying very hard to be good owners. ALL advice is welcome!
