Congrats to sukistorm for guessing the last cat! It was Spottedleaf! Here's the next one...

Darkest fur,
Prophecy spoken,
Wind in his pelt,
Heart to be broken,
Loved the girl,
Of silver fur,
Rocky place,
Sadness awaits,
She died very sadly,
So he could be happy,
Journey awaits,
Feather forever,
Warrior new,
Saved one from Thunder,
Loved her like another,
Kits to be born,
Father unknown,
Mate with another,
As to be loyal,
Saving his son,
From dark breeze,
Couldn't be with the one.

Who am I?
((Sorry this ones really long!))
