You know, now that I think about it, WHY does the author keep mentioning at every intro that humanity's birthrate is in decline?
Is that in anyway related to why cats can now talk?

Theories:
-Humanity is being slowly replaced by cats as the dominant intelligence species on the planet somehow.
-Something else caused their birth decline, so humans enhanced cat's intelligence artificially to be their emotional companions, to have someone to talk to at the final years of humanity
-Same as above but with unwholesome implications for cat's new intelligence and their bonds with humans...
