I recently moved both of my pythons into plastic tubs with a newspaper substrate; in generaly, it's been great -- humidity & temperatures are stable and they seem happy. The only problem is that the tubs can be _too_ good at keeping in the humidity: when the snakes pee they produce a decent volume of liquid, which takes the humidity up to 95-98% (from 55%).

It's normally not a big deal, because I clean up the mess and everything's fine; however, I'll be away for a week and the only person who can check on them for me is only willing to check temp/humidity, not to clean & feed...so if they pee while I'm away, they might end up stuck in very high humidity for a while.

I'm thinking about switching to a coconut substrate while I'm away, since it would absorb more of the liquid. (If it works nicely, I might even make it a permanent switch.) Has anyone else had a similar problem? Any other suggestions?
