The indoor-outdoor debate for companion cats involves genuine welfare tensions between behavioral freedom and safety risks. Evidence-based approaches can provide enrichment while managing the most serious hazards.
The indoor-outdoor decision involves real welfare considerations on both sides. Outdoor access provides behavioral enrichment, environmental complexity, and expression of predatory and exploratory behavior that indoor environments cannot fully replicate. However, outdoor cats face genuine mortal risks and their predation on wildlife causes welfare harm to billions of other animals annually. Supervised outdoor access, enclosed garden spaces, and leash walking provide meaningful compromise solutions. The welfare goal is providing the benefits of environmental complexity without the mortality and ecological costs of uncontrolled outdoor roaming. Individual cat personality and local environment should inform case-by-case decisions.
