Wow, I can't believe how many people use paper products. I guess it's because most of you have several herps. Myself I have one 20 gallon terrarium containing 2 very young BPs. One normal and one Black Pastel. Since I only have one tank it has a 2 inch deep layer of "All Living Things"(petsmart brand) Fir mulch. It holds moisture well and is just rough enough to encourage good shedding. Sidenote: I just got these snakes on Monday and today they had their first meal. I would post pics but mine don't want to show up when I attach them. Any ideas on that?
