Indoor cats require adequate territory to express natural behaviors and avoid the chronic stress of insufficient space, requiring active environmental management.
Indoor cats require thoughtful environmental management to compensate for the small physical space of typical homes. Vertical space through cat trees and wall shelves, multiple resource locations, hiding places, and visual barriers all effectively expand the territory available to indoor cats. In multi-cat households, territory adequacy is determined by the most stressed cat's ability to access resources without confronting others.
