During the Man-Kzin Wars, a strange religious faction appeared within the Kzinti ranks, worshipping the ideal of Kdapt. Kdaptism preached that the Creator made humans and not Kzinti, in his own image. Though this religion was most often the venue of low-born families, there were a few Kzinti in the greater nobility who also subscribed to Kdaptism.
When Kdaptist disciples prayed, they wore masks of human skin in the hopes of confusing the Creator long enough for the Kzinti to win the war. Human psychologists suggest that hundreds of years of steady losses of their greatest warriors tore at the social and psychological infrastructure of the Kzinti race, who believed their destiny to be no less than domination of the universe. The disbelief created by the losses in turn created Kdaptism.
When asked for their opinion about this theory, Kzinti mutter something untranslatable in the Hero's Tongue.
