TCB, I hope you're feeling better today.
We always keep a light or two on in the house at night so we can see where we're going. My large black love cat, Bailey, sleeps under my dresser next to the heating vent and it's easy to step on him if I'm not paying attention.
When he gets too hot, he climbs into bed between us and snuggles in under the covers. It's kind of like those bed warmer things they used to use with coals from the fireplace in a metal container on a pole. Except alive.
