At 4am on Saturday morning I awoke, thirsty and confused. I went downstairs (without turning the lights on) and as I walked through the living room it seemed somehow populated. I turned on a small light in the kitchen, fetched my glass of water, and went back into the living room. In the dim light from the kitchen I could just discern small cat indistinctly but thoroughly eating a mouse on the rug, while senior cat relaxed on the sofa. Neither cat looked up as I watched them, and after I'd had my glass of water I politely turned off the light and went back to bed.
In the morning, no trace of the mouse could be found, not even the smell of it.
