Our house is old, needs siding and insulation (although we do have a new roof and new windows) and it's VERY drafty. We put plastic up over the entire 3 sided front porch effectively killing all use of the front door.

WINTER - temp. is 70-72 degrees Farenheit when we are home (at that we feel chilly) and when we are not home the programable thermostat goes down to 62. The cats don't like it that chilly but we do have the heated pet bed, numberous warm fluffy pet beds, and several afgans and quilts out for them to use.

SUMMER - We only have a VERY old and HUGE window A/C that was given to us for free. We only have one outlet in the house that can handle the load and unfortunately we have an open house type floor plan that the A/C just wasn't designed to handle a space that large. We only run it when the temp gets up to 90+ degrees in the house, or on the rare occasion that one of the cats seems to be having difficulty with the heat. In which case we run the thing wide open which on a very hot humid day only gets the temp down to 75 after 2 solid days running 24/7 but it's better than nothing.
