It's November here and not as cold as it will get in December and January when temps will be between -10F and -30F below if we have a cold winter.  Lows now are only in the 20s & 30s.

We have two cats.  Only one goes in the heated cat house.  His bed seems moderately warm, but by not as warm as expected.  Perhaps it will be warmer in there when the true cold temps arrive.
