Aromatherapy, Diffusers & Exposure

How to Use Fragrance Safely Around Pets

Introduction

In Part 1 of this series, we explored what’s inside candles and how certain ingredients can affect pets. But even a thoughtfully chosen candle or fragrance can become a concern if used in the wrong environment or too frequently.

In this post, we’ll discuss how ventilation, the amount and frequency of use, and your pet’s species all play a role in fragrance safety. We’ll also address one of the most common questions from pet owners: Are essential oil diffusers safe to use around animals?

How Exposure and Environment Affect Fragrance Safety

Even gentle scents can become overwhelming or irritating if exposure is too high or the air isn’t circulating. This is true for humans, and pets. Here’s what to keep in mind:

1. Ventilation

• Good airflow is crucial. Always use scented products in well-ventilated areas such as open windows, or keep doors ajar to let fresh air move through the space.

• Why it matters: Poor ventilation can trap fragrance, making the air more concentrated and potentially irritating, especially for pets with sensitive respiratory systems (like cats and birds).

2. Amount and Frequency

• Less is more. Lighting a single candle occasionally is very different from burning several every evening.

• Why it matters: The more products you use, and the longer they’re active, the greater the chance of irritation, particularly in smaller or enclosed spaces.

3. Your Pet’s Species

• Cats: Especially sensitive due to differences in how their bodies process certain compounds. They’re more likely to be affected by airborne fragrance.

• Dogs: Generally less sensitive than cats, but still have strong senses of smell and can react to strong or persistent scents.

• Birds: Extremely sensitive to airborne particles and vapors. Even small amounts of fragrance can cause issues. It’s safest to avoid using fragranced products around birds altogether.

 Note: Cats don’t have the liver enzymes (like glucuronyl transferase) needed to break down certain compounds in many essential oils.

Essential Oil Diffusers and Pets

What You Need to Know

Diffusers release essential oils into the air as tiny droplets, which pets can inhale or absorb through their skin or fur. Here’s what to consider:

Potential Concerns

• Essential oils are concentrated. Some, even in small amounts, can cause discomfort or adverse reactions in pets—especially cats and birds.

• Common oils to be cautious with: Tea tree, eucalyptus, clove, citrus, peppermint, and others (see Part 1 for a full list).

• Signs of overexposure may include drooling, lethargy, unsteadiness, vomiting, or breathing difficulties.

When Diffusers May Be Lower Risk

• Using very diluted essential oils

• Diffusing only occasionally

• Keeping pets out of the room while the diffuser is running

• Ventilating the space thoroughly before allowing pets back in

Important: The risk increases with prolonged use, poor ventilation, or if pets are confined to the area during diffusion.

Tips for Safe Use of Diffusers and Aromatherapy

• Avoid using oils known to be problematic for pets.

• Never use a diffuser in the same room as birds.

• Don’t allow pets to rest directly next to or underneath a diffuser.

• If your pet has asthma or respiratory issues, avoid diffusers altogether.

• Never apply essential oils directly to your pet unless specifically directed by a veterinarian.

Signs Your Pet May Be Sensitive to Fragrance or Diffused Oils

Watch for these signs and act promptly if you notice them:

• Lethargy or unusual tiredness

• Drooling

• Stumbling or wobbliness

• Vomiting

• Difficulty breathing

• Tremors or, in rare cases, seizures

If you notice any of these symptoms:
Turn off the diffuser, move your pet to fresh air, and contact your veterinarian right away.

Final Thoughts

Aromatherapy and diffusers can add a lovely scent to your home, but it’s important to be mindful of how they might affect your pets. With good ventilation, moderation, and ingredient awareness, you can enjoy fragrance while keeping your furry (or feathered) friends comfortable and safe.

Coming Up Next

In Part 3, we’ll look at everyday fragrance use, like perfumes, room sprays, deodorants, and even cleaning products. How do these impact pets, and how can you keep your home smelling great without overwhelming your pet’s senses?
