I have an electric dehydrator. I preserve harvest and dry seeds with it. But it leaks a lot of heat. I wouldn’t call it an efficient appliance. But if the furnace is on anyway, any heat it loses is just heat the furnace didn’t have to make, so no biggie. But also, the cats love sitting on it while it’s warm. So the cat bed function stacks on the room heater function on top of the food dehydrator function.
That got me thinking. I also have an indoor winter plant tent for growing chiles all winter here in the far north. I leave the door unzipped except when I’m containing ladybugs inside. And 2/3 of the cats like to bask in the “sun” and warmth there.
My cats are helping my
permaculture. ;-)
