That's why I wrote it's 3.3x more expensive, not 3x
10% of the energy is wasted on things like bodily functions, growing, running around and bringing joy to people.

I would expect the cat to be closer to 100% efficient than the furnace, unless it spends its time sitting on a window sill behind the curtain radiating towards infinity
