Broad is bemoaning the lack of useful warmage in her crapper, and I can definitely concur; this sucks.
When I was a kid, Gramps had bue ticks. Big, stinky smelly dogs. Partially smelly because t hey had a habit of sleeping in the crappers. Or on them, to be more accurate.
See, Gramps had indoor plumbing but for many years they;’d used an outhouse, and it was still there. Hell, if someone was using the house crapper, you STILL used the outhouse.
So as often as not, you had to chase off a dog. There was an old horsehair brush there, to sweep off the ticks and fleas that the dogs generally left on the seat- and we always dosed the dsamned thing with a liberal sprinkling of flea powder once or twice a week- but man, the seat was always warm when you sat.
Once I remember having to push the thing off it’s foundation so a dog could scrape his way out, having fallen down the hole. And I remember more than one cold fall evening, shooing a dog off a hole, and sitting down on the warm seat, scritching said dog betwixt the ears in thanks for keeping my place.

Do you know why the dogs were on the crapper to start with?
Yep, not only was it a shelter, but the rotting waste at the bottom of the hole made its own warmth, so the seat-hole would be marginally warmer (think chimney) than the floor and much warmer than the outside.
Smart dogs.
I figured it hadda be sommat like that slash.
Maybe you could use the phenomenom of the Blue Tic seat-warmer to come up with a term that describes a toilet seat so recently vacated that it is soothingly pleasant to use. What litle creativity tha
…that deigns to visit my skull has escaped me.
