The debate between indoor and outdoor cat keeping involves genuine welfare tradeoffs. Understanding the evidence helps cat owners make informed decisions about their pets.
Indoor-only keeping protects cats from external hazards but creates welfare challenges from confinement in an environment that cannot fully meet their behavioural needs. Without appropriate enrichment, indoor cats develop boredom, obesity, and frustration. Outdoor access provides environmental complexity, exercise, and expression of natural behaviour — but at the cost of significant mortality risk and wildlife predation. Compromises including enclosed gardens (catios), harness walking, and high-quality indoor enrichment can substantially improve indoor cat welfare. The conservation case for keeping cats indoors in urban and suburban areas is strong where wildlife populations are vulnerable.
