The grey kitten walked into the living room. He paused to lick his back foot.
The brown kitten sprang to his feet and leaped down to the floor. When he landed, he hunkered down low and walked slowly up to his brother. He reached out and poked him in the paw.
The grey kitten looked at him.
The brown kitten looked back. Something went wrong with his surprise attack. As he walked away he repeated to himself…sneak first, attack second. Sneak first. Attack second.
