Can I use essential oils around cats, dogs, and small pets?

No, not without precautions. Essential-oil compounds can irritate the airways, skin, and eyes of cats, dogs, birds, rabbits, and small animals in ways that don't affect humans. Cats are especially sensitive because they can't metabolise certain oil compounds. Don't diffuse or mist essential oils where pets spend time, ventilate thoroughly, and consult your vet before using any oil.

⚠ Don't diffuse or mist around pets

Keep sprays and diffusers out of rooms where cats, dogs, birds, rabbits, or small animals spend time. Essential-oil compounds can irritate airways, skin, and eyes in ways that don't affect humans. Cats are especially sensitive because they can't metabolise certain oil compounds.

No diffusing No misting Especially cats

✓ Ventilate and consult your vet

Oils linger in soft furnishings, carpets, and curtains. Air out the space thoroughly before letting pets back in. Every species and breed has different tolerances, so your vet can confirm what suits your household before you use any essential oil.

Air out first Ask your vet

What should I watch for if my pet is exposed to essential oils?

Watch for sneezing, drooling, watery eyes, tremors, vomiting, laboured breathing, lethargy, or unusual behaviour. Cats may also groom excessively or hide. If you notice any of these after scent exposure, open windows to ventilate, move your pet to fresh air straight away, and call your veterinarian. Wipe spilled oil with mild soap and plenty of water, and follow your vet's advice before washing oil off fur or skin.
