The city-state idea still doesn't make sense (to me).  If kats on Katworld
are social enough to organize cities and the concept of rank, then they're
social enough to form nations.  But think about something:  The biggest
metropolis in the world, Tokyo/Yokohama/Kawasaki, Japan, has 26 million
people, but Japan as a whole has 125 million people, a 1:4.8 ratio.  The
second largest, New York, has 16 million, and the U.S. as a whole has 264
million, a 1:16.5 ratio.  Then there's still Oosaka/Kyooto/Koobe,
Nagoya/Gifu, Sapporo, and other large cities in Japan which take other huge
chunks out of the population.  Same in the U.S.  My point is while the vast
majority of the Earth's population lives in cities, that doesn't mean ALL of
the Earth's people live in cities.  In physically large nations like U.S.,
Australia, China and Russia, the people aren't evenly distributed.
Australia, another example, has about 18 million people, but when you take
away Sydney, Melbourne, Brisbane, Adelaide, Perth and Canberra, there aren't
that many people left.  But also take in mind that not all nations are large
in area, but still have a lot of people, with some rural land to spare.
Singapore: 2.9 million people; 247 sq. mi.  Mauritius: 1.1 million people;
788 sq. mi.  Compare to New York City's five boroughs: 7.3 million people;
301 sq. mi., or Los Angeles (not including surrounding townships): 3.5
million people; 465 sq. mi.

My point is that Katworld may not be that different from Earth. =^^=
