The question of outdoor versus indoor access for cats involves genuine welfare tradeoffs that evidence-based owners and policy makers must navigate carefully.
The outdoor access debate reveals genuine tensions between different welfare goods. Indoor cats live longer on average but may experience frustration of natural behaviours including hunting, territorial exploration, and climbing. Outdoor cats express natural behaviours but face chronic low-grade stress from territorial disputes, traffic, and predators. The 'right' answer depends on individual cat personality, local environment, and owner capacity for environmental enrichment. Cats that are indoor-only require substantially richer environments to meet their behavioural needs.
