Distant Early Warning

Alexandre Dumas’ cat knew when he was coming home:

At the time I speak of, I held a situation in the service of the Duc d’Orléans, with a salary of 1500 francs. My work occupied me from ten in the morning until five in the afternoon. We had a cat in those days, whose name was Mysouff. This cat had missed his vocation; he ought to have been a dog. Every morning I started for my office at half-past nine, and came back every evening at half-past five. Every morning Mysouff followed me to the corner of a particular street, and every evening I found him in the same street, at the same corner, waiting for me. Now the curious thing was that on the days when I had found some amusement elsewhere, and was not coming home to dinner, it was of no use to open the door for Mysouff to go and meet me. Mysouff, in the attitude of the serpent with its tail in its mouth, refused to stir from his cushion. On the other hand, on the days I did come, Mysouff would scratch at the door until some one opened it for him.

“My mother was very fond of Mysouff,” he wrote. “She used to call him her barometer.”
