All you cheap newspaper people!!! Not sure if its true but I have heard from a few people that large snakes kept on newspaper have developed what they call "pancaking' where the snake cant really get a grip on the stuff so it will flatten itself out to try and grip more and after years, they lose their shape. I heard mostly from boa guys. Not sure if it's BS or not but it does make sense as the newspaper slides all over.

Have heard of guys taping the newspaper to each other so it cant slide under itself leaving exposed cage flooring. I still say just use a real substrate. If you only have a couple snakes, its going to be fairly cheap. Heck even with my snakes, I only go through about 1 brick of ReptiChips a month and that's with 7' and 5' boas who piss all the time and a retic who is like a mini fire hose permanently attached to a hydrant lol.
