I was thinking about that but reasoned that the room is usually very dry and the cage is completely open mesh.. The water doesn't stay there for more than an hour or two, particularly under the lamp, and the snake seems to enjoy lying on the leaves until they dry vs. soaking..
As long as the cage isn't wet for longer than about an hour a day, do you still think that will cause problems?
:Misting the cage daily can be a problem for the snakes tho.....The snakes need a dry cage with just a water dish to drink and soak in. If the cage stays to humid they can develop skin infections.
