Cat Chronic Stress Physiological Effects

Chronic stress causes measurable physiological harm in cats. Understanding the biological effects of stress motivates better welfare management.

Key Facts

Chronic stress suppresses immune function, increasing infection susceptibility
Elevated cortisol over time causes gastrointestinal effects including idiopathic cystitis
Stress-related over-grooming causes psychogenic alopecia in some cats
Social stress in multi-cat households is a major chronic stressor
Reducing environmental stressors has measurable physiological benefits

Welfare Considerations

Cats experiencing chronic stress suffer physiological harm beyond behavioural signs. Immune suppression, gastrointestinal disease, and skin conditions from chronic cortisol elevation represent real health impacts that reduce lifespan and quality of life. Managing the environment to reduce chronic stress has physiological as well as behavioural welfare benefits.

What You Can Do

Identify and reduce chronic stress sources in your cat's environment
Provide resources including multiple hiding places, feeding stations, and litter trays
Consider environmental modification and pheromone therapy for chronically stressed cats
