i just moved into a house and was hoping to keep the herps and the rats in the same room--the rats being set up in the closet area. this is NOT working, i think because the room is too small and doesn't have good enough ventillation.

anyhow, i would like to move the rats out to the garage but this will require some sort of heating for them. it doesn't get terribly cold here during the winter for very long, but it does get down into the 30s at night for about 2 months out of the year. anyhow, i would like to use a gas heater as this seems to be the safest and most economical way to heat the area. i'm looking for any recommendations from people that use this type of heater--which specific one do you use or which would you recommend?
