The cougar awoke into a blue night of rust and went out to investigate. All the cities were crumbling, and rivers bled ferrous water through the streets. It followed their streams, meowing but hearing no answer. All the buildings had been grayed with a film of petrified ash. It was a dirty white cougar of the ancient white mountains. It had traveled through the rock countries and had played with shards of broken glass and reams of tape, miles and miles of twisted tape and roll film left to blacken in the ever blue twilight. It did not know how long it had hibernated, but it had never imagined awakening to a world without sun and only the light of strange stars. In some of the streams, it found suspicious fish, and ate them raw. It meowed at the lampposts that still flickered, and listened intently to the automated factories still threshing and smelting and refining even though there was nobody left on the face of the machine planet. It investigated the reservoirs and shops where there were headless mannequins in lingerie or phonographs that played without end. And it stopped to listen and to scratch at things, and it wondered if everything were hiding in the music. And what did music mean?
