Morning: windowsill, east side, until roughly eleven. Midday: the router. I have asked him not to. He does not care. Afternoon: the patch of carpet by the balcony door, which moves, and so does he. Evening: on top of the fridge, near the back, where the motor is. Night: on me. He is nine years old and has never once been wrong about which spot is warmest. I have started using him as a thermometer.
