Visiting Featherstar

Deadstar stared out into the moorland, his eyes seeming to look farther than they actually were. A hint of longing twinkled in their deep blue depths. Longing for one of the last cats on the earth that he loved, and that was precisely Featherstar, the small, pretty WindClan leader. She'd once been a fellow warrior in ThunderClan with Deadstar, until Rainstar had come and asked her to move to WindClan, for it had been dying.
It broke Deadstar's heart, but he'd never stopped loving her. He could never let her go again; never let love slip away from his grasp ever again. It had managed to escape his heart about a million times, with the loss of his family, friends, and the leaving of his mate.
His heart never stopped aching.
And now, Ebonyroot had told him of her untimely death.
His voice came out in low, flowing tones, and his right front paw tapped a beat. "Oh where, oh where, did my heart slip to... Oh where oh where did my heart slip to..." He didn't realize he was singing.
Is it even possible for cats to sing?
Apparently, yes.

The stars above cried out, one shining brighter than the others. Thunder crackled over head, and a rainstorm's clouds covered the moon, as rain poured down on Deadstar's singing figure. Each drop was a tear of their own.
