Hi, So I just set up a 1.4 mouse colony. They're living in a 10gal (30gal in a couple days, once I dig it up) tank. I suppose I might split the tank into two colonies once I get some births.

Anyway, They're living in the garage because they smell way too bad to have in the house. The garage isn't heated.

I picked up some RV tank heater pad deals (something like flexawatt). I was thinking If I'd stick that on the bottom of the tank and rig a thermostat, and maybe a lamp or two on top, they'd be ok in the winter?
I thought I should probably add styrofoam on most sides too, I guess.

It's been known to get down to -40 or worse here, but the garage is usually somewhat better (being semi-detached, insulated).

I guess I'm just looking for input, if anyone has a similar setup.
