KREATIVITY FOR KATS by Fritz Leiber GUMMITCH PEERED thoughtfully at the molten silver image of the sun in his little water bowl on the floor inside the kitchen window. He knew from experience that it would make dark ghost-suns swim in front of his eyes for a few moments, and that was mildly interesting. Then he slowly thrust his head out over the water, careful not to ruffle its surface by rough breathing, and stared down at the mirror cat — the Gummitch Double — staring up at him. Gummitch had early discovered that water mirrors are very different from most glass mirrors. The scentless spirit world behind glass mirrors is an upright one sharing our gravity system, its floor a continuation of the floor in the so-called real world. But the world in a water mirror has reverse gravity. One looks down into it, but the spirit-doubles in it look up at one. In a way water mirrors are holes or pits in the world, leading down to a spirit infinity or ghostly nadir.
Gummitch had pondered as to whether, if he plunged into such a pit, he would be sustained by the spirit gravity or fall forever. (It may well be that speculations of this sort account for the caution about swimming, which is characteristic of most cats.)
