You are right, cats do not kill rats. The rats are too big for a cat
to kill a full grown rat, babies maybe. Cats specialize on mice,
voles and other small rodents. The real rat killer is a dog. They are
big enough and strong enough to take on a rat and win. You need a
good sized strong hunting type dog, and they will get rid of the rats
and enjoy the challenge.


Your point is well taken. Still, if you kill enough babies, the vermin dies
out.

Some say this is what's happening to political liberals in the US (see "Roe
Effect").

For example, there were 75,000 abortions in Florida in 1980. Were it not for
the abortions, those 75,000 would have voted in their first election in
2000. Bush won Florida by 500-odd votes and with it, the presidency. How
would those 75,000 missing votes influenced the outcome?
