The energy of life ran strong in his veins and sinews. Once and again as that, which was for him imaginative vision and anticipation, asserted itself, he crisped his strong claws into the crumbling mortar, shooting them, by an unconscious muscular action, from the padded sheaths in which they lay. Once a furious yapping sounded from a lighted window far beneath; but he scorned to do more than turn a slow head in the direction of it: then once more he resumed his watch.
The time came at last, conveyed to him as surely as by a punctual clock, and he rose noiselessly to his feet. There again he paused, and stretched first one strong foreleg and then the other to its furthest reach, shooting again his claws, conscious with a faint sense of well-being of those tightly-strung muscles rippling beneath his loose striped skin. They would be in action presently. And, as he did so, there looked over the parapet six feet above him, at the top of the trellis up which presently he would ascend, another resolute little head and blunt-spired cars, and a soft indescribable voice spoke a gentle insult. It was his friend … and, he knew well enough, on some high ridge in the background squatted a young female beauty, with flattened ears and waving tail, awaiting the caresses of the victor.
As he saw the head above him, to human eyes a shapeless silhouette, to his eyes a grey-penciled picture perfect in all its details, he paused in his stretching. Then he sat back, arranged his tail, and lifted his head to answer. The cry that came from him, not yet fortissimo, sounded in human ears beneath no more than a soft brokenhearted wail, but to him who sat above it surpassed in insolence even his own carefully modulated offensiveness.
Again the other answered, this time lifting himself to his full height, sending a message along the nerves of his back that prickled his own skin and passed out along the tail with an exquisite ripple of movement. And once more came the answer from below.
