Well, a similar sort of thing is going on in my very own neighborhood, with the local cats.
All of them; well the six or so that I have seen, are very territorial. Especially my cat. She constantly prowls around her territory (which spans across 6 properties), on the lookout for intruders. It it very similar to military patrols etc.
When other cats are detected, war begins. And all the cats in the neighborhood do this. Six cats fighting for land adds up to a disaster. As my royal cat is the biggest of them all, her territory continues to expand, and she is always in borderline wars.
If her territory grows any larger, she will be patrolling so often that I will barely ever see her.
The life of a cat.
