Whether to allow cats outdoor access involves genuine welfare trade-offs between behavioral freedom and significant risks including predation, traffic, disease, and toxin exposure that affect both individual cats and wildlife.
The indoor-outdoor question for cats has no universal right answer but requires honest weighing of welfare trade-offs. Outdoor access provides genuine behavioral benefits for many cats, but the associated mortality risks and wildlife impacts are real and significant. Compromises — catios, supervised outdoor time, leash walking — can provide outdoor stimulation while managing risks. The welfare case for purely indoor living requires compensatory enrichment investment; the welfare case for outdoor access requires honest acknowledgment of the costs.
