Indoor cats need significant environmental enrichment to express natural behaviours and maintain psychological wellbeing.
Indoor cats avoid the road traffic, disease, and predation risks of outdoor life but face different welfare challenges — restricted territory, limited stimulation, and frustrated hunting drives. Environmental enrichment for indoor cats must address multiple motivational systems: climbing, hunting, hiding, grooming, and social play. Without adequate enrichment, cats become overweight, develop anxiety, and may exhibit stress behaviours including overgrooming or inter-cat aggression in multi-cat households. Enrichment investment is one of the highest-return welfare improvements for indoor cats.
