The debate over indoor versus outdoor cat keeping involves genuine welfare trade-offs between behavioral freedom, environmental enrichment, and exposure to road and predation risks.
The indoor/outdoor debate involves genuine tensions between different dimensions of welfare. Cats kept entirely indoors avoid road mortality and infectious disease but face increased risks of behavioral frustration, obesity, and associated metabolic disease if environmental enrichment is inadequate. Outdoor access provides critical exercise, cognitive stimulation, and expression of predatory and exploratory behaviors. The welfare solution lies in risk management rather than total restriction - secure garden enclosures, supervised outdoor time, and traffic-calming road design can preserve behavioral freedom while reducing mortality risk. The wildlife impact of outdoor cats is a separate ethical consideration alongside their own welfare.
