Someone else’s cat lies on my desk while I’m working, if you can call what I am doing – admiring a calico cat – work. Her chest moves up and down, drawing in oxygen and pushing out carbon dioxide. At one end, her eyes peer out of almost closed slits. At the other, eight inches of soft furry tail wave slowly, its tip articulating like bait, though I have no idea what she wants to attract. Maybe she’s flirting with the human.
