>>1098874Uhhh yeah a lot.
>>1098889is not a bad suggestion.
The Man-Kzin Wars series in Larry Niven's Known Space universe comes to mind. A peaceful future Humanity makes first contact, and it's with a warlike race of cat assholes and they go back and forth conquering and enslaving each other for a century or two. Lots of short stories. There are numerous short stories about the races the Kzinti (cats) enslave in their interstellar empire as well.
I guess Mote in God's Eye and Footfall, both also Larry Niven work as well.
