Alexander Dumas (1802-70)
A cat is the emblem of restlessness and impatience at the same moment. A restless cat no more remains in the same place than a silk thread does which is wafted idly to and fro with every breath of air. A cat on the watch is as motionless as death stationed at its place of observation, and neither hunger nor thirst can possibly draw it away from its meditation.
from The Three Musketeers (1844)
