Thanks for the answers, this really helped me a lot! I was thinking about getting a clear rubbermaid container so she can see the daylight outside and not have to worry about all that then. Well that's good, and a whole lot less money. So for food, seeing how pinkies are too small for them, what's a good feeder mouse for them? A fully grown one? And for temperature control, seeing how I'll be using a rubbermaid container, will a heat mat burn through the plastic? I'd use the heat tape, but I'm no wiring expert and I may just end up messing it up in the process. And should I keep the lid on or off, and if on, should I make a hole there?
