Are Essential Oils Safe for Dogs and Cats? A Guide for Pet Owners

More and more people are choosing natural essential oils to enjoy the benefits they offer around the home. One of the most common questions I’m asked is:

Are essential oils safe for dogs and cats?

Essential oils can be used cautiously in homes with pets, but they must be properly diluted, well ventilated, and never applied directly to animals. Some essential oils are considered toxic to pets, and birds should never be exposed to airborne fragrance.

Before using essential oils around animals, it’s important to understand why pets respond differently to scent than we do.

Why Are Pets More Sensitive to Essential Oils?

Dogs have a far stronger sense of smell than humans. Their noses contain significantly more scent receptors, allowing them to detect extremely small concentrations of aroma molecules. A fragrance that feels subtle to us can be far more intense for them. Humans can also become temporarily accustomed to scent, a phenomenon known as nose blindness.

Cats are also highly sensitive, and certain essential oil compounds are metabolised differently in cats, increasing the risk of toxicity.

Birds are especially vulnerable due to their highly specialised respiratory systems. Because air circulates continuously through their bodies, airborne fumes and fragrance can cause serious harm.

For this reason, caution and ventilation are essential whenever scent is used around animals.

Are Essential Oils Safe for Dogs?

Dogs can be around diffused essential oils if they are used sparingly and in well-ventilated spaces. They should always be able to leave the room freely.

Never apply essential oils directly to your dog’s skin and never allow ingestion.

If your dog has asthma, respiratory conditions, or other chronic health issues, avoid diffusing essential oils unless advised by a qualified veterinarian.

Are Essential Oils Safe for Cats?

Cats are generally more sensitive to essential oils than dogs.

Because some essential oil compounds are processed differently in cats, diffusion should be very limited, well-ventilated, and never used in confined spaces.

Never apply essential oils directly to cats, and always seek veterinary advice before using essential oils in a home with cats.

Essential Oils That May Be Toxic to Dogs and Cats

Some essential oils are considered higher risk for pets and should not be used around them in concentrated form. These include:

• Tea Tree

• Rosemary

• Thyme

• Cinnamon

• Cassia

• Fennel

• Wintergreen

• Eucalyptus, particularly for cats

• Citrus oils, particularly for cats

Exposure risk increases with high concentration, poor ventilation, or direct contact.

Can Essential Oils Ever Be Used on Animals?

Essential oils are used in animal aromatherapy in some parts of the world, including within holistic veterinary practice. However, this is carried out by trained professionals in controlled environments, using carefully selected oils, precise dilutions, and species-specific knowledge.

It is not the same as diffusing oils at home or applying them independently.

Essential oils should never be applied directly to pets unless under the supervision of a qualified veterinary professional trained in their use.

How to Diffuse Essential Oils Safely Around Pets

If you choose to diffuse essential oils in a pet-friendly home:

• Use half the recommended amount.

• Diffuse for short periods only.

• Ensure excellent ventilation.

• Allow pets to leave the room freely.

• Monitor behaviour for signs of discomfort such as sneezing, drooling, lethargy, or agitation.

Keep essential oil bottles tightly sealed and stored safely out of reach. If ingestion or exposure occurs, contact your veterinarian immediately.

Are Candles and Reed Diffusers Safe for Pets?

Any product that emits fragrance, smoke, vapour, or fumes should be used cautiously around animals.

Reed diffusers release fragrance slowly and passively, making them generally less intense than active diffusers, but good ventilation is still essential.

Candles, including soy candles, should never be burned in enclosed spaces with pets present, particularly birds.

A Note on Birds

My partner and I have had Cockatiels for over 20 years, and we do not diffuse oils, burn candles or use strong cleaning products anywhere near them. They have their own space in the house.

Birds have highly specialised respiratory systems, making them extremely vulnerable to airborne toxins. Even small amounts of fragrance, smoke or fumes can cause serious harm.

If you own birds, avoid all fragranced products in shared airspace.

Frequently Asked Questions
