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

Born of sand,
Leafy fur,
Sweetest kit,
Medicine new,
Captured and met,
Friendship set,
Traveled along,
Thunder for long,
Fell for love,
Ran away,
Loving one,
Kits forelay,
Sister kept,
Them in check,
Found them out,
Kicked away,
Apprenticed one,
Blind from sight,
Asked her back,
Went she did,
Herbs in mind,
Still sweet under lid.

Who am I?
