Heard about this from a friend. Story about race of alien cat type people who capture other aliens and turn them over to be hunted by a race of shape shifting aliens. Human in the story is caught while sailing solo across the ocean. Human is then placed in confinement with a 7 foot t-Rex alien? Looking for a title on this one.
Larry Niven had a bunch of short stories and a few novels about the Kzinti who were warrior type race of bipedal cat-aliens with a variety of themes, including some bounty hunter stories, I believe. It's been so long since I've read any of them and I only read two or three, so this is just a suggestion.
