How enrichment functions as preventive medicine by reducing stress-related disease and behavioral problems in companion animals.
Enrichment as preventive medicine reframes behavioral welfare provision from optional enrichment to essential health care. The physiological mechanisms linking chronic stress to immune suppression, gastrointestinal disease, and behavioral deterioration are well-established. Animals in enrichment-poor environments experience these consequences at rates that translate into measurable veterinary costs. Enrichment provision that prevents these downstream consequences reduces both animal suffering and the costs associated with treating stress-related conditions. This framing makes the economic case for enrichment investment that welfare arguments alone may not achieve in all contexts — particularly in institutional settings including shelters, boarding facilities, and veterinary practices where animals are held.
