Agreed. And the fact Saki and Satoru, and perhaps others, now think they are getting closer to humans will only accelerate their evolution, if indeed the stray thoughts of cantus users during their sleep affect those outside of the towns. If they are already predisposed to consider them close to humans, their subconsciousness will only grant them more human characteristics. It will also be troublesome in the sense that once they get too close, humans might not be able to fight back anymore due to their conditioning. The cats won't stand a chance against heavily armed armies, either.
