I'm just brain storming right now, and it doesn't have to be reptile carpets. I just want something that doesn't mold. Strangely enough that all my substrate mold, for my pacmans I understood because the service aren't always dry. But the substrate for Marshmallow is always dry via the heat bulb.

And I found out this morning (around 3 - 4 am) that Marshmallow is having a hard time climbing the glass. Is there anyway to solve it? Seeing her try so hard breaks my heart because there is nothing much I can do.
