What type of substrate do you use?

Indented craft paper. :) Absorbent, I like the color, and one roll lasts forever.

I have been thinking about changing from newspaper to indoor/outdoor carpet, because it would look nicer. I figure i can just cut a bunch of pieces to the right size so i can just replace it while cleaning the dirty one. Would anybody advise against this?

i use zilla bark, makes it nice and humid, in the exo terra which is screen top it khelps keep it from being TO! humid..

Right now I'm using Jungle Earth but I'm going back to Aspen. I like the natural look too.

Sani chips and paper towels. depending on what I have more readily available at the time.
