Indoor cats require deliberate environmental enrichment to meet their behavioral needs. A poorly enriched indoor environment causes chronic boredom, stress-related illness, and behavior problems that reduce welfare and human-animal bond quality.
Indoor cat welfare is frequently compromised not by active harm but by environmental poverty — a home that does not provide the stimulation, vertical space, foraging opportunity, and social interaction that cats need. Chronic under-stimulation produces stress-related conditions (over-grooming, aggression, idiopathic cystitis) and behavioral problems that are expressions of welfare failure. Environmental enrichment is not expensive or complicated: wall shelves, window perches, puzzle feeders, and regular interactive play sessions transform a barren indoor environment into one that supports natural cat behavior. The return on investment — in cat welfare and reduced veterinary costs — is substantial.
