This is the first day I’ve been able to turn off the cat warmers after this past week of freezing temperatures. At night, I open the cabinet doors to keep the pipes warm, but Precious the Puppy will tear everything out of the cabinets when she’s up so during the day I was just keeping this cat warmer near the cabinets with the doors shut. I have a couple more I’ve had running at other key locations, and I think I got through this first bad winter spell with no frozen pipes except possibly one drain line on the outer wall of the cellar. I have pipes in some places that are just about impossible to protect, but so far, not bad for this winter’s pipe protection plan! All main pipes got through just fine. And all the cats are warm…..
