Indoor cats require active environmental design to meet their behavioral needs for hunting, vertical space, hiding, and social engagement.
Indoor cat enrichment is an active welfare responsibility, not a passive condition. A cat in a small apartment with a food bowl and a litter box is not enriched — it is under-stimulated in ways that contribute to obesity, anxiety, and behavioral problems. Creating an enriched indoor environment requires deliberate design: vertical spaces, hiding opportunities, foraging experiences, hunting play, and social engagement all contribute to positive welfare. The investment is modest but requires ongoing attention to maintain novelty and engagement rather than allowing the environment to stagnate.
