Yep you were right....here goes the debate!
I acutally don't like the shredded aspen bedding.....I lost a western hognose (Heterodon nasicus nasicus) to an impaction from some accidentally ingested aspen. Personally I use the product called CareFresh....it's a recylced wood pulp product that is safe if ingested, cleans up really nice and allows the snakes to burrow. It's not as nice looking as a lot of the wood products (it's just kind of grey), but I actually use it on ALL my snakes...garters, kings, ect. I know Scott Felzer also uses it for his garters. I've heard some people say it's too dry, but I've NEVER had any shedding issues with my snakes and they all have complete sheds.
