For some reason I've been thinking of using Aspen, if not for my ball pythons, at least for my corns, as my Zim loves to burrow into the substrate. Right now she's just on paper towels. Paper towels are cheap and easy for me. I pay about $6 for 8 rolls and they last me a while (I change them 1-2x per week), but Aspen just seems like it would help them thermoregulate better, give them more security, and I've heard you can simply spot clean (remove obvious feces and urate) and change it completely less often than using newspaper or paper towel.
I can get aspen for snakes at work, but normally its around $7 for a small bag. I have a lot of tubs to fill. They have aspen for small animals for a little more money but you get a big bag. I think it's around $10-15 per big bag (can't remember the exact amount). I've been to Southern States, a farm/garden supply store near me and they have aspen designed for horse stalls and such. They advertise it as kiln dried aspen. Would this work for snake bedding? Or it is not soft enough and possibly dusty? It is only $7 per huge bag.
In the end, I may just stick with paper towels as that is what is working for me right now. But it is something I've been thinking about lately and thought I'd get some opinions on whether that aspen would be safe, or would it be better to use the small animal or snake aspen.
