Hola_Lilz  and -Dawnsky-  guessed correctly. Unfortunately, they both guessed at the same time, so I hafta do more typing. The last cat was Deadfoot... Yay. Here's the next riddles:

My brother, killed by a powerful cat,
I seeker revenge on that cat and tried to kill him.
But eventually, I forgave.

~~~~

I was rejected by my love,
I am a killer,
I was the mother of three long lost kits.

Guess both correctly, and you win! :)
