i used to have a leopard gecko and i just used paper towels as substrate because it was exactly the width of the cage. It just looked so boring though (white paper) and i kind of felt bad for the gecko because its natural habitat obviously isnt paper.... do you think it makes a difference to the bp if it has nice shredded coconut substrate or paper?

edit:can someone explain what the things in peoples sigs is thats thats like "1.2.wild type ball python"
