Providing environmental complexity for indoor cats reduces stress and improves welfare. Vertical space, foraging opportunities, and sensory variety are evidence-based enrichment tools.
Indoor cat enrichment is one of the highest-impact welfare improvements accessible to cat owners. The behavioral needs of an obligate carnivore evolved for active hunting, territorial exploration, and complex social negotiation are poorly met by passive indoor environments. Evidence-based enrichment - foraging, vertical space, sensory variety - actively promotes positive welfare states.
