Last night I sat up later than usual, trying to finish untangling a wool skein. About 9.45 Daisy came out, practically looking at her little purrket-watch, and started head-butting me and messing about with the yarn. "I'll come to bed when I've finis this," I said. I could alm hear the "Humph!" in response. She went off, and a moment later I heard prolonged digging and covering in the litter. Went to check it, and yes, she'd done her second poo for the day, and was sitting on the bed looking pleased with herself. "All right, all right, I'll pack up and come to bed!" I said, and showed her her bribe worked. She was a happy cat!
