His movements had started as slow wobbles, dragging an overfull belly across the floor of the den, blind eyes and folded ears doing little to aid his search for the warmth that was always there, not big like the food warmth, but small, like him. He didn't like it when he couldn't feel it, hear it. She had always been there, even before he could remember. Now that they were out in the big wide space, he didn't want to lose her.
Days turned into weeks and eyes cracked open. Tiny folded ears unfurled and the world seemed even bigger now that he could see it. Strength had come to his limbs and he no longer wiggled but wobbled instead, and once the wobbled were under control he walked.
It was an accident, really, that he managed to find himself out here squinting at the bright (grey, clouded sky) and the very loud sounds. He had been having fun with his sister, safe where they knew they should say, and her tackle had been so unexpected that he rolled right out into the muted light. When the movement finally stopped, he sprawled out on the ground in awe. "Nnnnoa!" you gotta come see this! Then more insistently, "NNNNOA!"
The little boy growled his frustration, and the sky growled back.
