Sorry aspen for snakes i personally feel is only for looks. Its messier for you, cost more money, and has no humidity advantages over newspaper/paper towels. Now if you like the look go for it, but for looks cypress does a lot better job in the looks/humidity/cost areas. Heck i think you can get 2 cubic feet at lowes for about $6. Its up to you, but $14 for 4 cubic feet or $24 for 8 cubic feet of aspen is a little too much for me.
