Indoor cats face significant behavioral deprivation compared to outdoor cats, requiring systematic environmental enrichment to meet natural behavioral needs for hunting, climbing, and exploration.
Indoor confinement extends cat lifespan significantly by removing predators, vehicles, and disease exposure. However, removing outdoor access also removes the primary source of behavioral enrichment - hunting, territorial exploration, and environmental novelty. Owners who keep cats indoors for welfare and safety reasons have an obligation to compensate for this restriction through active enrichment provision. Cats without adequate enrichment develop obesity, behavioral problems, and stress-related illness that reduce quality of the longer life indoor living provides.
