Indoor cats require carefully designed territory that meets their instinctive needs for vertical space, secure retreat, and environmental control.
Indoor cat territory welfare reflects the mismatch between cats territorial adaptations and the typically simplified indoor environments many cats inhabit. Cats map their territory three-dimensionally; a flat apartment without vertical space provides a tiny fraction of the territory complexity a cat is adapted to navigate. High perches and elevated routes through the home allow cats to access the height they would use in natural environments to survey for threats and feel secure. Multiple resting zones that cats can choose between based on their current state needs and social situation reduce chronic territorial stress. The welfare improvement from thoughtful indoor territory design is measurable through reduced stress indicators, lower veterinary visits for stress-related illness, and positive behavioral indicators.
