that is a matter of opinion. I have used aspen, coconut bark, and paper towels and didn't have a problem with either. I like the aspen and coconut bark because it keep and holds humidity well, but the paper towels make it MUCH easier to clean.

Did you pay for it? I think I saw where you adopted it so I assume you paid an adoption fee or was given to you for free. Hope you didn't pay Lucy prices for it.
