Short Answer
Lavender scent is not universally safe for all cats. Some cats tolerate mild lavender fragrance in well-ventilated spaces, while others may experience discomfort from strong or prolonged exposure. Cats have highly sensitive noses, and concentrated lavender oils, diffusers, incense, candles, or room sprays may cause irritation, avoidance behavior, sneezing, or restlessness. The safest approach is keeping scents light, optional, and allowing cats to leave the area freely.
