I keep mine out of my bedroom. I slept out in the room with their cages a few nights to see if I could catch them being active, but they're pretty silent. Sometimes I peek in on them during the night though, and find them elsewhere than their usual spot. Last night was a first, I actually caught my biggest girl in the act of actually drinking from her water dishI always assumed she got enough from the couple of daily mistings, but I guess that's what the water dish is there for.
