Yep I use mostly unprinted stuff.. but a few snakes still get the printed. I hate getting ink all over my fingers, but hey the stuff is free.

I change out the newspaper every week.. it sure is nice getting cages sparkly clean and it's so easy with newspaper. I use 1-2 layers usually. And I usually crumple up a couple extra pieces as hiding spots. My colubrids love it that way.
