basic fact about human beings: the farther apart they live, the more pleasant their relations are. The ﬂip side: the closer together, the more ﬁghts and murders. Stating the obvious, there are more assaults and murders in cities than in rural areas. This seems to apply to cats as well.
Jam a lot of cats together in a city, and you can count on some loud nocturnal battles among toms attempting to stake out their territories. And no wonder: a farm cat might have ten acres to himself, while city cats have to share a relatively tiny amount of space. “Good fences make good neighbors” doesn’t apply if you are small, agile and can easily climb on the tops of the fences!
