Can I use a diffuser if I have a cat?

Never apply essential oils to your cat's fur or skin. As well as being absorbed through the skin, your cat could also lick the oil off their fur and swallow it as they groom. Inhaling essential oils from products such a reed diffusers or plugin diffusers can also be dangerous to cats and may have psychological effects.
