Allowing cats outdoor access improves their welfare through natural behaviour expression, but road traffic is the leading cause of traumatic injury and death in owned cats — creating a genuine welfare dilemma for owners.
The outdoor access decision for cats sits at the heart of a genuine welfare dilemma — the richer behavioural life available outdoors against the substantial mortality and injury risk from roads. Neither blanket indoor confinement nor unrestricted outdoor access is universally optimal: the right answer depends on local traffic density, available outdoor space, individual cat temperament, and whether enriched indoor environments can compensate for outdoor restriction. Managed outdoor access through catios, supervised garden time, or enclosed garden systems provides a welfare compromise that captures behavioural benefits while controlling the most severe risks. The welfare case for road safety measures — speed reductions, cat-friendly road design — is compelling and under-advocated.
