The debate between indoor and outdoor access for cats has evolved: welfare science now supports nuanced strategies that balance enrichment with safety.
The indoor-outdoor cat debate has often been framed as binary, but welfare science supports a more contextual approach. High-risk environments (busy roads, dense predator populations, high cat density) argue strongly for indoor-only or enclosed outdoor access. Lower-risk rural environments may support outdoor access with manageable welfare trade-offs. The key welfare principle is that indoor environments must be actively enriched — a barren indoor life is not a welfare win simply because it is safer. Catios, supervised outdoor access, and high-quality indoor environments can achieve the best of both: safety and behavioural fulfilment.
