It gets harder every year. I set the thermostat to 40 F, dress warmly and use space heaters. The birds get two heat lamps and an electric blanket at night and on extra cold days. (Belladonna has discovered how to nap ontop of the cockatoo's cage.) We manage. The cats and dog develop lovely coats. It doesn't do my artheritis much good though. Last winter was rough. This year I will probably shut off most of the rooms and the guys and I will make do with a smaller space. Hopefully the guys will get along well enough for this to work. Added body heat might help with that! Wisconsin gets cold!
