Indoor cats live in environments that restrict natural behaviors including hunting, territory exploration, and vertical movement, making active enrichment essential for psychological welfare.
Indoor cat welfare requires active management of environmental richness to compensate for the behavioral opportunities that outdoor access provides. A cat with outdoor access can hunt, patrol territory, climb trees, and engage with novel stimuli daily. An indoor cat in an unenriched environment may spend most of its active hours in behavioral deprivation — the feline equivalent of boredom and frustration. The welfare solution is not to release cats outdoors (which creates significant wildlife welfare problems through predation) but to create indoor environments rich enough to engage the predatory, social, and exploratory behavioral systems that cats need to express. Interactive play, puzzle feeding, vertical space, window access to outdoor stimuli, and for social cats appropriate feline companionship can meet these needs without the outdoor welfare risks.
