I agree, paper towels are great for quarantine but I personally hate it for them permanently. It looks like they don't really enjoy crawling on it or least mine looked like they hated it. They love aspen though especially Dottie when she was a baby and Vicky now as she is still a baby. Seems babies love to burrow in it. I still change it out completely every month as I'm rather OCD about my snakes cages too as they are out a lot and on me and I don't want a poop or pee covered snake crawling around on me :P
