If cats are part of your family and you like using essential oils to support your family’s health, please read this article as it introduces you to the safe use of essential oils with and around your cats. It also provides important tips regarding precautions you can take with essential oils that may be potentially toxic to your cat but would benefit your own health. Learn how to use these essential oils in a safe and responsible manner that does not negatively impact your cat’s health.

Why can essential oils be a problem for cats?

Cats are sensitive to essential oils for a few reasons.

  1. Cats have a very acute sense of smell.
    Cats have twice as many receptors in their olfactory ephithelium than people and also have a scent organ in the roof of their mouth.
  2. Cats have delicate and thin skin.
    Anything applied topically will have quicker absorption into the bloodstream. Remember, when diffusing essential oils into the air, there will still be absorption through the skin, just in lower ratio than what is absorbed through inhalation.
  3. Cats lack important liver enzymes that humans posses.
    Cats can’t efficiently metabolize some of the compounds in certain essential oils, which can lead to toxic build-up in their bodies over time (glucuronosyltransferase (UGT) enzymes).

 

Does this mean that all essential oils should be avoided?

No. But perhaps the question that needs to be asked first is what is the quality of the essential oils used? Many essential oils available in stores today are adulterated, of very poor quality,  and often created synthetically in a laboratory. Those essential oils can contain many unnatural, harmful elements. Even if they are extracted from plant materials, they can contain chemicals from solvent extraction, pesticides, heavy metals, microbes, mold spores, fillers, and other unhealthy or unnatural components. Since we know cats are highly sensitive to chemicals and artificial ingredients, it could be that the toxins in inferior oils are the real culprits when cat owners have had bad experiences even with essential oils from the “SAFE” list (see below). 100% pure therapeutic grade essential oils can benefit your cat’s health when used appropriately. Please don’t be fooled, only because a bottle says 100% pure it can still contain all the harmful elements mentioned above. To learn about which questions to ask and how to determine whether your essential oils are of therapeutic, medicinal grade – read this article on essential oil quality.

 

Essential Oils that can be potentially toxic to cats

Cats can’t efficiently metabolize phenols, ketones, d-limonene and alpha-pinene, so over time toxic buildup can occur.

Examples of essential oils containing higher amounts of Phenols – Wintergreen, Anise, Birch, Clove, Basil, Tarragon, Fennel, Oregano, Thyme, Mountain Savory, Peppermint, Melaleuca (Tea Tree), Calamus, Cinnamon Bark, Citronella, Marjoram, Nutmeg, Eucalyptus citriodora, Parsley, Ylang Ylang. These all contain greater than 8% phenols.

Examples of essential oils containing higher amounts of Ketones – Western Red Cedar, Idaho Tansy, Marigold, Spearmint, Thuja, Hyssop, Davana, Sage, Dill, Yarrow, Peppermint. All these oils contain greater than 20% ketones.

Example of essential oils containing higher amounts of D-Limonene – Grapefruit, Bitter Orange, Orange, Tangerine, Mandarin, Lemon, Celery Seed, Lime, Bergamot, Angelica, Dill, Neroli, Blue Tansy, Citronella and Nutmeg.

Examples of essential oils containing higher amounts of Alpha-pinene – Cypress, Cistus, Pine, Douglas fir, Juniper, Myrtle, Rosemary Verbenon, Silver Fir, Angelica, Nutmeg, Eucalyptus, Dill, Spruce. These are all monoterpenes that have alpha-pinene concentrations greater than 15%.

Essential Oils that may be used with cats with CAUTION and only by a holistic veterinarian or certified aromatherapist: Black Pepper, Cardamon, Carrot Seed, Celery Seed, Cinnamon Bark, Citronella, Clove, Galbanum, Ginger, Juniper, Palmarosa, Petitgrain, and Western Red Cedar.

If your cat has liver or kidney trouble make sure to avoid essential oils high in Ketones, Phenols, D-Limonene, and Alpha-pinene.

7 Essential Safety Tips for Cat Owners

Just because an essential oil is toxic to you catsdoes not mean that you can never use it in your home to support your own health. However, it does mean that certain precautions will need to be taken to ensure your cat is not exposed to the essential oil.

Here’s a list of tips to help keep your cat safe:

  1. Pick from the “Safe” list whenever possible.

Select essential oils from the “Safe” list whenever possible to support the health and wellness of your family, including your cat. Make sure it is a 100% pure therapeutic grade essential oil, free of fillers, pesticides, heavy metals, microbes, mold spores, fungi, or other harmful ingredients.

  1. Diffuse using common sense.

When diffusing an essential oil from the “Safe” list, make sure to only diffuse small amounts for limited periods of time, and make sure your cat has the freedom to leave the room if it wants. If you want to inhale an essential oil that is potentially toxic to your cat but would be beneficial to support your respiratory system for instance (Eucalyptus, Peppermint, Clove, Melaleuca), try to diffuse in your car using an ultrasonic USB diffuser, at work, use a personal inhaler (making essential oil inhalers is a great way of enjoying the aromatic benefits of essential oils without diffusing it.), or use a room your cat never spends time in. This way you can fully benefit from the inhaled use of essential oils and keep your pet safe. Never diffuse an essential oil that is potentially toxic to your cat in a room it spends time in.

  1. Don’t pet your cat after touching essential oils.

If there is any residual essential oil on your hands and you pet your cat, the oil will get on its fur. Cats lick themselves for cleansing purposes. Your cat would be in danger of ingesting the essential oil from its fur. So be cautious and wash your hands well after using essential oils.  In addition, make sure to keep the skin that you applied an essential oil to covered (long pants, long sleeved shirt, etc.) so that your cat does not rub up against you and accidentally transfers the essential oil onto its fur. Apply a drop under the soles of your feet in the morning and put on socks/shoes immediately. Click here for more information about topical use of essential oils.

  1. Store essential oils away from pets and kids.

Cats are very curious, mischievous,  and playful capable of getting into almost anything. Even if your essential oils are sealed tightly, there will be residual oil on the bottle that your cat could lick off or get on its fur. Keep your essential oils stored in a box or cabinet your cat can not open. Same rule goes for young children. Keep your essential oils locked away and out of reach.

  1. Be cautious cleaning with essential oils.

Essential oils are wonderful additions to natural cleaning products but use caution and common sense, making sure your cat does not rubs against the surface you cleaned or licks it, to avoid ingesting essential oils.

  1. Don’t leave out dishes after cooking with essential oils.

For those of you who love to enhance flavor and therapeutic value of your dishes with essential oils, it is important to put away or clean these dishes immediately after use. Make sure your cat doesn’t eat leftover food that was prepared with essential oils.

  1. Appropriately dilute for topical use with cats.

Essential oils are very potent and powerful. If you have decided to use an essential oil from the “Safe” list topically to support your cat’s health be sure to highly dilute the essential oil. I generally use the safety considerations for use of essential oils with babies. which means a 0.5% dilution ratio.
