The decision to allow cats outdoor access involves balancing the enrichment benefits of natural behaviour against risks including road traffic, predation, and disease, with evidence informing welfare-optimal choices.
Neither fully indoor nor fully outdoor cat management is universally welfare-superior. Outdoor access provides vital enrichment, exercise, and behavioural expression but exposes cats to trauma, infectious disease, and territorial conflict. Indoor-only cats are protected from outdoor risks but face elevated rates of stress-related conditions when enrichment is inadequate. A hybrid approach with enclosed garden access or supervised outdoor time provides many benefits of outdoor enrichment while reducing mortality risks. Welfare decisions should be tailored to individual cat needs, personality, and local environment.
