my thermostat is set at 70 in the winter and now that I'm home all day I keep it there. Before then I would have it turn itself down during the hours when no one was home but only to 60. But that was all before I had bullies. Ever since the boys came to live with us I've been home so the temp stays the same. My boys don't seem cold even when the house is colder than 70. For instance, right now it is only 57 degrees outside but we have our door open and the heat has not been turned on and my thermostat is saying it is 70 in the house and the boys seem okay. I can usually tell when they get cold because they will move closer together and sleep in a pile.
