Key Takeaways

  • Essential oils and hydrosols can be toxic to cats, especially those with liver or respiratory issues.
  • Cats are highly sensitive to phenolic compounds in essential oils, which can cause liver damage, respiratory issues, or poisoning.
  • Keep essential oils, diffusers, and potpourri out of reach of cats to prevent accidental ingestion or exposure.

Essential oils, aromatherapy, and potpourri in your home may be pleasant for you, but natural compounds in these fragrances can be dangerous for your cat. Take precautions when using these products so your cat does not have a toxic reaction. If your cat has any liver impairment, it may be best to eliminate these products from your cat's environment.

Essential Oil Toxicity to Cats

Certain essential oils were once considered to be safe for cats.

Warning

However, compelling evidence has now demonstrated that essential oils can be toxic to cats, whether taken internally, applied to the skin, or simply inhaled. Exposure can lead to serious liver damage, liver failure, seizures, or even death for cats.

Cats lack certain enzymes that provide the ability to properly metabolize the various compounds in essential oils, phenols in particular. These phenolic compounds occur naturally in some plants and are highly concentrated in essential oils. The liver is most often the organ which is affected by essential oils.

Essential Oils Potentially Toxic to Cats

These oils are known to contain phenols and be toxic to cats:

  • Wintergreen oil
  • Peppermint oil
  • Citrus oil (including lemon oil)
  • Tea tree oil (melaleuca oil)
  • Pine oil
  • Eucalyptus oil
  • Cinnamon oil
  • Pennyroyal oil
  • Sweet birch oil
  • Clove oil
  • Ylang ylang oil

Higher concentrations of essential oils increase the risk to your cat. If your cat accidentally ingests any oils, seek veterinary care immediately.

Symptoms of Essential Oil Poisoning

Cats absorb oils that are directly in contact with their skin. Oils diffused in the air are inhaled which can cause respiratory issues. They can also collect on the fur, which results in your cat ingesting them during licking and cleaning. Toxicity can occur very quickly or over a longer period of exposure.

Signs of Essential Oil Poisoning in Cats

  • Drooling
  • Vomiting
  • Tremors
  • Difficulty walking, wobbliness (ataxia)
  • Respiratory distress (wheezing, fast breathing, panting, coughing)

If you notice any of these signs, move your cat immediately to fresh air, and contact your local veterinary emergency center right away. The veterinary center may have you call a poison hotline for additional guidance on treatment. The veterinarian may note a low heart rate, low blood pressure, and signs of liver failure.

How Your Cat May Be Exposed to Essential Oils

Your cat may be exposed to essential oils you use for your own purposes. Keep any essential oils in a cat-proof cabinet so your curious pet doesn't have access to them. Passive reed diffusers or potpourri pots can be knocked over, exposing your cat to the oil-containing liquid which can be ingested or absorbed on it's skin or fur with contact. Don't allow your pet to lick your skin if you have applied any products that contain essential oils.

Essential oil and aromatherapy diffusers, candles, liquid potpourri products, and room sprays are sources of airborne essential oils that cats can inhale which leads to respiratory irritation. If you can smell the fragrance of the oil, there is oil in the air and it can affect your cat.

Kittens, elderly cats, or cats who have liver or respiratory problems should be kept out of any room where essential oil diffusers are used. Don't wear aromatherapy jewelry when you are around your cat.

The Danger of Hydrosols

Hydrosols are often touted as a more natural, safer alternative to essential oils. Hydrosols are also known as "flower waters" as they consist of the water that remains after steam-distilling flowers or herbs in water, and are less saturated than essential oils.

While hydrosols are safer for use on human skin since they do not have to be diluted, they still are dangerous for cats and other pets. The water can hold on to residual matter from the plants that can be toxic if ingested or even inhaled.

Some pets can tolerate hydrosols, but others are more sensitive. Limit your pet's access to them and their scents to minimize the risk of any health issues.

FAQ
  • What should I do if my cat is exposed to essential oils?

    If your cat shows any signs of essential oil poisoning like drooling, vomiting, or difficulty breathing, immediately move your cat to fresh air and contact your local veterinarian. They may also refer you to a poison hotline for further assistance.

  • Which rooms in my home are safest for cats if I use essential oils?

    Keep your cat away from rooms where essential oil diffusers are actively used, especially if your cat is a kitten, elderly, or has liver or respiratory issues. Ensure essential oils are stored securely in cabinets where your cat cannot access them.

  • Are there safe alternatives to essential oils for freshening up my home?

    Consider using non-scented cleaning products or opting for feline-friendly plants, and always ensure that any product you use is safe for your cat.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
