Outdoor access provides enrichment and behavioural opportunities for cats, but also exposes them to significant risks. Balancing freedom with safety is a key welfare consideration.
Neither fully indoor nor fully outdoor living is universally optimal for all cats. Welfare depends on the individual cat's temperament, age, health, and local environment. Cats with strong outdoor motivation who are confined indoors without adequate enrichment can develop chronic frustration, obesity, and stress-related urinary disease. Equally, outdoor cats in high-traffic urban areas face acute welfare risks from accidents and fighting. The welfare-optimal approach is individual assessment: providing secure outdoor access where possible, and high-quality indoor enrichment where outdoor access is genuinely dangerous.
