Outdoor cats face multiple risks that significantly shorten their lives and cause welfare harm, with evidence-based management reducing but not eliminating these threats.
Managing outdoor cat risks requires honest acknowledgement that free-roaming outdoor access comes with genuine welfare costs. Neutering dramatically reduces roaming and associated risks; curfew management reduces traffic mortality during peak danger hours; vaccination protects against infectious disease; regular parasite treatment reduces subclinical disease burden. The welfare comparison between enriched indoor life and outdoor access with management is individual — some cats have strong outdoor drives that make full indoor confinement welfare-problematic, while others adapt well to indoor life.
