Cats have a unique metabolic system that differs significantly from humans and dogs. Their livers lack a crucial enzyme called glucuronyl transferase, which helps break down and eliminate various chemicals, including compounds found in essential oils such as phenols and terpenes.

As a result, these substances can build up in a cat’s body over time, leading to toxicity—even from small or diluted amounts.

1. Inhalation

Essential oil particles dispersed through diffusers, sprays, or scented candles can be inhaled by cats. Because cats have sensitive respiratory systems, this exposure may lead to irritation or respiratory distress.

2. Ingestion

Cats may lick surfaces where oils have been used or groom themselves after coming into contact with an oil-contaminated area, ingesting the substance in the process.

3. Skin Absorption

Essential oils can also be absorbed through the skin. Even petting your cat after applying a scented lotion or oil can unintentionally transfer the substance onto their fur.

Recognizing the signs of essential oil toxicity is vital for early intervention. Common symptoms include:

• Drooling or pawing at the mouth

• Vomiting or diarrhea

• Difficulty breathing

• Lethargy or weakness

• Uncoordinated movements

• Seizures or tremors

• Skin irritation or burns

If you notice any of these symptoms and suspect exposure, contact your veterinarian immediately.

Several essential oils commonly used in households can be highly toxic to cats. These include:

• Tea Tree (Melaleuca)

• Eucalyptus

• Peppermint

• Citrus oils (lemon, orange, grapefruit, bergamot)

• Cinnamon

• Clove

• Pine

• Wintergreen

• Ylang Ylang

• Oregano

• Thyme

• Pennyroyal

These oils are often found in cleaning products, diffusers, personal care items, and scented candles.

This topic is widely debated. Some experts suggest that extremely diluted amounts of certain essential oils may be tolerated by cats under strict conditions—like good ventilation and no direct contact. However, due to the unpredictability of cat reactions and the lack of comprehensive research, most veterinarians recommend avoiding essential oils altogether in homes with cats.

That said, some home fragrance products—like certain candles or wax melts—are made without essential oils or use very small percentages that are considered safe when used responsibly. For example, some brands offer products that are essential oil–free or contain only minimal concentrations, making them more suitable for pet-friendly spaces.

Some products, like those offered at Bedition Candle Co., are intentionally formulated with no essential oils, while others use low percentages that are gentle and non-toxic for pets when used as directed.

“Natural means safe.”

Not always. Many natural substances can be toxic to pets. “Natural” does not equal “harmless.”

“My cat has never had a problem before.”

Toxicity can build up over time. Lack of an immediate reaction doesn’t mean your cat is unaffected.

“It’s only a tiny amount.”

Even small doses can overwhelm your cat’s detoxification system. Cats are highly sensitive to concentrated plant compounds.

1. Remove your cat from the area immediately.

2. Turn off diffusers or extinguish candles.

3. Do not attempt to clean the cat’s fur without veterinary advice.

4. Contact your vet or a pet poison control center as soon as possible.

Never induce vomiting or apply home remedies without guidance from a veterinary professional.

Yes—but with extreme caution. Here’s how to reduce risk:

• Avoid using essential oils in enclosed areas

• Keep cats away from spaces where oils are being diffused or used

• Choose home fragrance products with no essential oils or only very low concentrations

• Always use them in well-ventilated spaces

• Monitor your cat closely for any changes in behavior or symptoms

If you’re unsure whether a product is safe, consult with your veterinarian or choose fragrance products made without essential oils.

While essential oils are popular for their wellness and fragrance benefits, they can pose real dangers to cats due to their unique biology and sensitivity to certain compounds. Exposure to even small amounts of some oils may cause toxic reactions—especially if used frequently or without proper precautions.

Still, you don’t have to give up enjoying scent in your home. By making informed choices and using products that are either free of essential oils or formulated with safe, minimal percentages, you can create a beautifully aromatic environment without compromising your cat’s health.

Always read labels, ventilate spaces, and consult your vet if you’re unsure. Your home can be both calm and cat-safe—no compromise required.

1. Can cats be around diffusers if I use pet-safe essential oils?

Even “pet-safe” or “natural” essential oils can still be harmful to cats depending on the concentration and exposure. Always ensure excellent ventilation and let your cat leave the room freely. The term “pet-safe” is not strictly regulated.

2. Is it okay to apply essential oils on myself if I have a cat?

Yes, but be cautious. Wash your hands thoroughly before touching your cat, and avoid close contact until the product has absorbed or dissipated.

3. Can I use cleaning products with essential oils in a cat household?

Use with caution. Avoid using toxic oils like citrus, tea tree, or eucalyptus in areas your cat walks or sleeps. Rinse thoroughly after use.

4. Do synthetic fragrance oils pose the same risks as essential oils?

Not always. Many synthetic fragrances are formulated without the specific compounds harmful to cats. Always look for phthalate-free, non-toxic options.

5. Are hydrosols (floral waters) safer than essential oils for cats?

Hydrosols are much less concentrated than essential oils and may be safer, but still require caution. Avoid spraying them near or on your cat.

6. How can I tell if a candle or wax melt is safe for my cat?

Choose products without essential oils or with very low percentages. Look for brands that disclose full ingredient lists and prioritize pet safety.

7. What should I ask a vet about essential oils and my cat?

Ask if a specific oil is safe, how to recognize toxicity, and what safe alternatives exist for home fragrance and cleaning.

8. Can kittens tolerate essential oils better than adult cats?

No. Kittens are even more vulnerable due to their size and underdeveloped organs.

9. Can I use essential oils in a room my cat never enters?

It’s lower risk, but not risk-free. Airflow and HVAC systems can carry particles throughout your home. Use air purifiers and clean surfaces regularly.

10. Do essential oils cause long-term damage in cats even if no symptoms show right away?

Yes, chronic exposure to certain oils may affect liver or kidney function over time. Subtle changes may go unnoticed until the damage is significant.
