No matter the brand, cats and essential oils are almost never a good idea. If you love your feline pets, do NOT believe the myth that "because our oils are so pure they are perfectly safe for ALL animals, including cats." WRONG! Cats and oils just don't mix, and there are ways to enjoy the therapeutic benefits of essential oils for yourself WITHOUT the danger of exposing your beloved cats to the oils.

Some of my favorite ways are inhalers by Dr. Frenchy and personal wearable diffusers by AromaJewelryPlus.

Essential Oils and Cats

Cats and Essential Oils

Cats lack the liver enzymes necessary to metabolize essential oils, and some oils can be toxic to cats. Unfortunately, cats have not only become very sick, but some have died following exposure or application of essential oils.

Oils Toxic to Cats





Citrus Oils - ALL citrus

Lavender (camphorous types)


Cinnamon cassia

Tea tree







Any oils containing phenols


Use the following with a great deal of caution and only if highly, HIGHLY diluted.

Certain oxygenated chemical constituents in some oils are particularly dangerous to cats. These are: Phenols, Ketones, and Monoterpenes. It's actually the thujone content in ketones and the carvacal in phenols that are the problem. Additionally, carvacrol is also part of the d-limonene found in all citrus.
