Last month a stranger in New Jersey asked permission to use the kzinti in his fanzine. (Fanzines, fan magazines, exist strictly for recreation.) Gary Wells wanted nothing of Known Space, just the kzinti, embedded in a Star Trek backgrounds
I wrote I hereby refuse you permission to use the kzinti in any literary property.
The last guy who did that involved the kzinti in a sadomasochistic homosexual gang, bang, badly, and published it on a computer network. A friend alerted me and we spoke the magic word and frightened him away. (Lawsuits) I'm still a little twitchy on the subject, so don't take any of this too personally…
Wells persisted. He sent me the Fleet bio for his kzin: a crewman aboard a federation battlewagon. He's got his format well worked out. It would have been fun to see what he might do with it; but I'm going to refuse him anyway. I don't want the playground getting too crowded.
I hope the network bandit doesn't turn up again.
I wouldn't be so picky with a story set in someone else's territory… but when you play in my playground you don't vandalize the equipment. Jim Baan and I have solicited stories which we bought and then rejected because they didn't fit my standards.
The bandit's kzin was ridiculous. Large warm-blooded animals that have to fight don't have big impressive dongs. There's no flexibility in their mating habits. (We have some partial understanding of why humans are an exception.) Humans will smell wrong; this is established as important to kzinti.
Yet such matters can be handled with taste, or at least verisimilitude.
If you once read Donald Kingsbury's Courtship Rite… but the nightmares have since gone away… "The Survivor" is your chance to get them back. Kingsbury writes horror stories for bright people. You will come to understand his cowardly kzin, and even to sympathize with him, but not, I hope, to love him. Grass-Eater is not normal.
"The Man Who Would Be Kzin," as portrayed by Greg Bear and S. M. Stirling, isn't normal either.
There are writers out there who know considerably more about the kzinti than I do. The Man-Kzin Wars authors have already delved deep into normal kzinti family life. The kzinti are mean and dangerous and intelligent. I fear I've been taking them too lightly.
