Outdoor enclosures (catios) offer cats safe access to outdoor stimulation while preventing wildlife predation, road accidents, and other hazards. They represent a welfare compromise that benefits both cats and ecosystems.
The tension between cat welfare and wildlife conservation creates a genuine ethical challenge. Cats are behaviorally motivated to hunt and explore outdoors, and complete indoor confinement requires compensatory enrichment that many owners do not provide. The catio model addresses this by providing sensory outdoor access, fresh air, sunlight, and novel stimuli without direct wildlife predation risk. Well-designed catios include vertical climbing structures, multiple perching heights, sheltered areas, and rotating enrichment. For cats with established outdoor habits, graduated transitions are necessary as immediate confinement causes significant distress.
