And afterwards, a cat slunk about through doors and office hallways, appearing not to be going anywhere . . . then gone.

Or was it the opposite? Maybe someone raised by cats had realized long ago they would never be a cat and should focus more on their non-cat ways and features. Who better to be a cat than a cat, and vice versa?

The cat or non-cat spotted a distant oval formation of birds gliding high above The City. These were funny, flappy, little things to catch and play with. Or maybe listen to and smile.

There they go. They pay no toll to enter and leave, far above and safe, with bellies full.

The cat, if a cat, slunk along further . . . then, again, gone.
