Indoor cats live safer but often less stimulating lives than outdoor cats. Evidence-based enrichment provides the mental and physical stimulation cats need to thrive, preventing behavioral problems and improving welfare.
Indoor cats face a welfare paradox - they are protected from the serious risks that shorten outdoor cats' lives, but at the cost of the stimulation, novelty, and behavioral expression that gives wild felid lives their richness. The hunting drive is one of the strongest motivational systems in cats - indoor cats that cannot hunt experience chronic frustration that manifests as over-grooming, aggression, destructive behavior, and obesity. Environmental enrichment is not a luxury for indoor cats - it is a welfare necessity that addresses the fundamental behavioral needs of obligate predators living in human homes. The goal is not to make indoor cat life merely safe, but genuinely fulfilling.
