None of the suppliers in this area can get Sani-Chips, but the last two times I've ordered and bought the aspen, it's been in two different forms? styles? from the same vendor. Almost like they changed processing methods.

The first was more flakes, and chips shaped. The second time was more shred-like, more fine and more fluffy instead of chunky. For clean-ups I prefer the second, but it doesn't last as long, and is a little more dusty. Snakes don't seem to care either way.

I'd like the chance to use the Sani, if I could ever find a source. But since my local feed store is now able to get the 9 ft3 "bales" of aspen, it's not as urgent a priority as it used to be.

Basically, I think it comes down to personal preference, the cost, and difference of maintenance (that you're willing to do) and is needed to provide the snake with the humidity it needs.
