And to pitch a little background into this discussion, I innocently
inquired here about three years ago as to how much water a cat heater
emits compared to, say, one's wife. This was after reading all the
warnings posted here about cracking windows to let heater moisture out.
Alastair volunteered to find the answer. Took the man a while to dig up
the details, but I reckon that now he knows the math, he's happy to
provide answers. And now I know that a cat heater makes a lot more water
vapor than Mrs Squirrel. Alastair is the best.
