Who is Speaker-to-Animals from Ringworld and what is their importance?

Speaker-to-Aminals is a result of a new generation of kzinti, tiger-like alien beings that are covered in orange fur. The puppeteers' experimentation killed off many of the kzinti in wars with the humans. Speaker is not as warlike as his fearsome exterior seems, though he challenges Louis to a life-or-death challenge when they first meet. He later admits that he wouldn't have followed through, since killing a human would possibly result in war. The kzin know that war with humans leads to death.
