Balancing the enrichment benefits of outdoor access against the substantial safety risks facing outdoor cats requires evidence-based management choices that consider individual cat welfare.
Cat outdoor access welfare involves genuinely competing considerations: outdoor cats access environmental stimulation, physical exercise, and behavioral expression that indoor environments cannot fully replicate, but they face dramatically higher mortality from traffic, disease, and predation. The welfare calculus depends on individual circumstance — a cat with rich indoor enrichment and catio access may have better welfare than an outdoor cat in a high-traffic area. The wildlife impact of free-roaming cats is also a welfare consideration for the billions of animals killed annually. Catios and supervised outdoor access represent the welfare-optimal compromise that most closely satisfies both cat behavioral needs and safety requirements.
