Balancing the welfare benefits of outdoor access against the risks cats face outside.
The indoor versus outdoor cat debate requires individualized welfare assessment rather than universal prescription, as both options carry genuine welfare costs and benefits that vary by individual, environment, and context. Cats evolved with outdoor behavioral repertoires that indoor confinement restricts, but outdoor environments in many settings expose cats to mortality risks that substantially shorten their lives. The welfare solution that best serves most cats involves providing outdoor access in controlled forms - enclosed gardens, catios, leash walking - that offer behavioral enrichment without the full mortality risks of free roaming. Conservation ethics around bird predation add a dimension beyond individual cat welfare to this calculus.
