Brandon_is_on_fleek guessed the last cat correctly! The answer was a cat! Idk. Anyways, here's the next one:

I am as black as night,
Sometimes I would think of family,
My mate didn't want me.

Have you read my new book yet? Guess That Medicine Cat! Go and read it! You promised me on the River of Styx.

Why are you still here? Right, to answer. But then you must go read, or you will get bad luck!
