This is the Rogue's Camp. All of the rogue cats of Twolegplace live here.
The Rogue's Camp is a common Twolegplace (houses, gas/petrol stations, stores, etc.) surrounded by a fence, and, beyond that, trees and the Twoleg Clans. The dens of the Rogue's Camp are made in a local park under trees, for protection. There is a fresh-kill pile in the center of the camp, which is the only thing not in a tree. Most of the day-to-day operations of the Rogues happen here.
