Domestic and feral cats kill billions of birds and small mammals annually, creating a major conflict between cat welfare and wildlife welfare.
The cat-wildlife conflict involves genuine welfare considerations on both sides. Outdoor cats fulfil natural hunting drives and benefit from environmental enrichment, but cause significant wildlife suffering at population scale. Indoor-only keeping eliminates predation but requires rich environmental enrichment to maintain cat wellbeing. Catios and garden enclosures represent a compromise that can protect wildlife while meeting cat behavioural needs. Time of day management — keeping cats in at dawn and dusk — reduces predation of the most active wildlife periods.
