Environmental modification using principles of feline behavioral biology can dramatically improve the welfare of indoor cats by meeting their territorial, hunting, and perching needs.
Indoor cat welfare is frequently compromised not through neglect but through failure to understand feline behavioral needs and provide appropriately enriched environments. A cat confined to a small apartment without vertical space, hiding spots, or hunting outlets may be physically healthy but experience significant behavioral welfare compromise. The link between environmental inadequacy and feline idiopathic cystitis is well-established - stress from insufficient territory or social conflict triggers inflammatory disease. Cats in under-enriched environments develop behavioral problems including redirected aggression, over-grooming, and excessive vocalization that are welfare indicators rather than behavioral defects.
