How providing appropriate environmental complexity meets cats' territorial needs and improves mental health and behavioral welfare.
Environmental inadequacy is one of the leading causes of feline behavioral problems and poor welfare in domestic settings. Cats confined to impoverished environments experience chronic stress, frustration, and conflict that manifest as inappropriate elimination, aggression, and overgrooming. Meeting cats' territorial needs through environmental enrichment is not a luxury but a welfare necessity. Providing appropriate complexity costs relatively little compared to veterinary treatment for stress-related conditions and dramatically improves quality of life.
