Understanding environmental stressors for cats and how chronic stress affects their health, behavior, and long-term welfare.
Environmental stress in cats creates a welfare problem that is uniquely insidious because cats show few obvious signs of distress until stress manifests as medical or behavioral problems. The link between chronic psychosocial stress and feline idiopathic cystitis illustrates how significant welfare consequences can develop from seemingly minor environmental disruptions. Cats experiencing stress from housing changes, unpredictable schedules, inter-cat conflict, or inappropriate environments develop physiological changes that predispose them to recurrent lower urinary tract disease, immune suppression, and behavioral disorders. The welfare-protective environment for cats provides predictability, safety, choice, and control: the ability to retreat from stressors, access reliable resources without competition, and experience their environment as stable and controllable.
