As soon as I get my next paycheck, I'm going to buy some of those digital thermometers, do they actually go inside the cage or on the outside? I see it has wiring so wouldn't want the snack to get wrapped in it. also I will buy a thermostat for the cage as I have yet to set up the heading pad.

Also, if I use tin foil, do I just leave it on top where the lamp will be? so just cut a piece of big enough for half of the cage then set the lamp on it?
