It going to be cold tonight.
When it's cold, the smart thing to do is divvy up the space into small units & heat only those that are necessary.
Rocky is under the covers. Missy's on top of them. The door is closed and I can still smell Daughter C's fire which warms the greater surrounds.
I'll go check on it.
Meanwhile. It's right toasty here with the little electric heater and warm mist humidifier running in this 12x12 dogxdog space.
