Determining the Effects of Essential Oils on Cats

Differentiating between which essential oils are safe to diffuse around cats and which ones are not is a complicated challenge. The perspectives are varied, so our mission with this article is to find the most consistent information among trained pet aromatherapy experts and share it with you.

In many articles, you will find a reference to the ASPCA website, which lists the plants and herbs that are toxic to cats. ASPCA covers the ingestion of such plants and herbs. However, there have not been enough formal studies to be certain about the effects of diffusing essential oils. Therefore, ASPCA is an excellent resource for the ingestion of plants, but not so much for diffusing essential oils.  

However, many people have used essential oils around their cats, and the goal of this article is to provide advice based on the views of qualified aromatherapists and Veterinarians. This article will discuss the safe use of essential oils around cats and provide a list of the best and worst essential oils to use around cats.

Disclaimer: Each cat is different. That’s part of what cat lovers most appreciate about their cats. It’s important to note that each cat is an individual, and can be allergic to certain plants and herbs just like each person can have differing reactions. Further, an individual may have a reaction to a botanical at one point in time that they may not have at another point in time. It is always best to check with your Veterinarian and an aromatherapist that specializes in animals before using essential oils around cats. Also be sure to carefully observe your cat after diffusing an essential oil. If you notice your cat behaving strangely or moving away from the area more than usual, the cat may dislike, or be experiencing adverse effects to the oil.

Catnip: Studies have shown that catnip aroma can send most cats into a euphoric silly state. Having a sensitivity to the nepetalactone constituent is an inherited trait in cats, and about 2 out of 3 cats will be affected by the aroma. Test out a very small amount to see how your cat reacts.

Petitgrain, coming from the twigs and leaves of various citrus trees, has a chemical make-up with similarities to lavender. Both are highest in linalool and linalyl acetate.

The aroma has provided peace to forest animals for centuries and reminds people of holiday celebration. The fresh scent may also have antimicrobial qualities to improve air quality and help with respiratory complaints.

The Worst Essential Oils for Cats:

This list was put together by exploring the official ASPCA and Pet Poison Helpline websites. While some users have found that their cats are fine around some of these oils, there is enough evidence out there to suggest that these are a risk to your cat.

Tea Tree: There are several accounts around the web of cats falling victim to tea tree oil. It is cited as toxic to cats on both Pet Poison Helpline and ASPCA. However, keep in mind that the ASPCA list is more focused on digestion than inhalation.

Peppermint: According to Pet Poison Helpline, peppermint essential oil is “known to cause poisoning in cats.” Dogs are also highly sensitive to this essential oil, so it might be best to avoid peppermint essential oil around pets in general.  

Wintergreen: According to several sources, including the Pet Poison Helpline and ASPCA, wintergreen essential oil can be toxic to cats. There are also several anecdotal examples of cats struggling around wintergreen essential oil.

Citrus: According to, “The stems, leaves, peels, fruit and seeds of citrus plants contain varying amounts of citric acid, essential oils that can cause irritation and possibly even central nervous system depression if ingested in significant amounts.” There have also been numerous reports of cat-owners whose cats are sensitive to citrusy scents. Petitgrain essential oil, however, is generally ok around cats. While it comes from the twigs of citrus trees, it does not contain the limonene constituent that has a citrusy aroma.

Pennyroyal: This essential oil is derived from a plant within the mint family. The essential oil is high in a chemical called beta pulegone, which has known hepatoxic, neurotoxic, and abortifacient effects (Tisserand & Young, 2016). It has unfortunately, been found in some flea powders, sprays, and fragrances to help get rid of fleas. Some pet owners have used it to ward off pests even though it should be avoided.
