The debate between keeping cats indoors or allowing outdoor access involves genuine welfare trade-offs that depend on the individual cat and environment.
The welfare decision about indoor or outdoor access requires balancing physical safety against psychological wellbeing. Cats kept purely indoors without adequate enrichment experience chronic boredom and frustration that manifests as overgrooming, aggression, and redirected hunting behaviours. Outdoor cats face genuine safety risks but also experience greater environmental complexity. The individual cat's personality, history, and local environment should inform this decision rather than a universal rule.
