I figured out which of several indoor cats was "the pisser" and she immediately became an outdoor cat. But knowing she lived a cushy indoor cat life for several years, I made her a cat house with a small electric blanket for the cold weather. I used a back heating pad for the blanket and it is sandwiched in between a thicker blanket she lies on. Worked great last winter - cat showed no sign of suffering from the cold. I kept that heating pad plugged in 24x7 for 4 months and it is still working great. Low wattage so not concerned about what little electricity it uses. I put a probe through the wall of the cat house to make sure it was warm enough. I recall getting an upper 40 degree reading on a pertty cold day and that seemed good enough. She has thick fur and is adequately fat. So anyway....I was thinking of getting some kind of radiant blanket to put on the roof directly above her. The hope is some of the blanket heat and some of her body heat will get reflected back down on her. I'm not sure what that shiny reflective stuff is called - the kind I'm picturing has a little thickness to it, not just a sheet of mylar. Think it is worth doing? A few degrees of reflected warmth could make a difference. Guess I'm feeling guilty and want to ensure she is comfortable. We're already having below freezing nights in Virginia. Oh yeah, the new carpet is nice. I'll miss the motorcycle.
