My cats have always lived indoors, in heated and air-conditioned space, and they can't read and probably wouldn't bother with the newspapers if they could. What's more, they are quite unaware of energy costs. Consequently, Watson and Isobel have no notion of climate change.

The different seasons affect them only to the extent that Watson's occasional dashes onto the front porch last about three minutes in summer and more like two seconds in winter.

All year round, they enjoy lounging on the vent gratings -- warm in winter, cool in summer. Can't beat that with a stick.
