Indoor cats have longer lifespans than outdoor cats but face distinct welfare challenges from confinement. Evidence-based enrichment creates genuinely good indoor cat lives.
Indoor cat welfare requires active management of an environment that, without intervention, fails to meet cats' behavioral needs. Cats are obligate predators whose behavioral repertoire is oriented around hunting, territorial behavior, and social structure. Indoor environments that provide no outlet for predatory play, no vertical territory, and no choice in social interaction leave cats chronically understimulated or stressed. The welfare case for indoor keeping is strong given the safety and lifespan benefits - but these benefits only outweigh the welfare costs if owners invest genuinely in enriched indoor environments. A bored, understimulated indoor cat has worse welfare than a managed outdoor cat.
