Indoor air quality significantly affects the health and welfare of cats, who spend most of their lives breathing household air that may contain harmful pollutants.
Cats's proximity to floors, surfaces, and household chemicals combined with their constant grooming makes them particularly vulnerable to indoor air quality problems. Unlike humans who may notice irritants and ventilate, cats cannot advocate for themselves. Responsible cat ownership includes being aware of hidden dangers: scented candles, air fresheners, non-stick cookware at high temperatures, tobacco smoke, and certain cleaning products all pose genuine risks. Improving indoor air quality is one of the most impactful preventive welfare measures available.
