>Cats--which as I recall are descended from African wildcats--are arguably the most successful carnivores around. They're incredibly adaptable.

I live in a village in Romania, a lot of cats get killed by cars, I always have an old cat that seems to be more smarted and survives for long time, but most younger cats get killed before 1 year. You would think they are smart and plus evolution that filters out the less adapted one the cats would be capable to avoid cars. Here we do not keep cats locked inside so it is sad but there is nothing we can do about this.
