Well done for Megan12721 for guessing the first cat! It was Firestar! Next cat here.....

I came from a family who had one extra thing,
I tried to make promises but they were on the wing,
I still feel grateful to one of dark stars,
My name tells but part of my fur and my paws,
I, as a warrior, was deputy to two,
Who wreaked danger and violence, but do you know who?
