Whether cats should have outdoor access is a significant welfare debate balancing natural behaviour against safety risks.
Both fully indoor and free-roaming lifestyles carry welfare trade-offs. Welfare science supports a nuanced position: fully indoor cats need substantial enrichment to meet behavioural needs, while free-roaming cats face real risks that can be partially mitigated by neutering, microchipping and traffic-conscious territory. Catios and leash walking offer compromise solutions.
