In a way that was Larry Niven's own fault for dusting off his short story "The Soft Weapon" - changing the character names and selling it for use to TAS for a quick buck. (I always laugh/get a kick out of the fact that Mr. Spock was the replacement for the Pierson's Puppeteer from that short storyI've always wondered if that's why Kzin never made it back into trek. Not only the problem of the TAS rights but then issues with Niven's state. Now that Ringworld is going to be a series, I suppose we'll never see Kzin on trek again. That's a shame. Like it or not, Kzin are where Niven's worlds and Star Trek meet.
