Last night when I was mning I suddenly realised that the cat was very interested in something in the corner of the kitchen. She had brought in a live mouse, and then let it go. I tried to get it with a brush and pan to put it out, but it was a feisty one and escaped.
I gave up and went to bed, half expecting to come down this morning to a body. I did think I heard some crashing around in the middle of the night, but no evidence of a dead mouse this morning.
Of course, the cat has lost interest and is sleeping in her radiator bed.
