I've been using paper towels for all my racks, and I am really fed up with those by now. The snakes always do their business under the towels, I can't spot clean, it looks terrible and the towels always end up wrinkled and torn in one corner. Plus, I don't like throwing away all this paper. I need to find a better option.

I've been looking at aspen as a different idea. The snakes would probably enjoy burrowing in it, and I'd be able to spot clean. I also wouldn't have to be guilty of throwing away so many paper towels. However, I've heard it gets moldy when wet and is awful for humidity.

Cypress mulch also seems like a viable idea, but I use it for one of my girls, and I don't like it very much... She's very good at getting it in her water. I do like how well it controls humidity if needed, but I'm not sure I'd like to use it for all of my snakes.

What are some other options? I'd like something that I can buy in bulk that isn't too expensive. Also, it has to be something that is unlikely to get in the water dish every single day.
