“Catnip Immunity and Alternatives § Breeding Cats To Increase Frequency Of Catnip Response”, Gwern2015-11-07 (cat genetics, catnip, R, Bayes, meta-analysis)⁠:

Estimation of catnip immunity rates by country with meta-analysis and surveys, and discussion of catnip alternatives.

I sketch out a threshold selection breeding program for increasing catnip response frequency. Based on Villani2011’s measured heritabilities of catnip response (corrected for measurement error), selecting exclusively responders would result in catnip response becoming nearly universal (~95%) within ~7 generations or potentially less than a decade.
