Essential Oils That Are NOT SAFE for Cats
Years ago, a woman consulted with me regarding essential oils for her cats who suffered from kidney and respiratory problems. Only one of her 5 cats was still alive when she consulted me. I deduced that she had inadvertently killed her cats with essential oils recommended to her by a certain multi level marketing essential oil brand.
Weeks ago, I offered to make a salve for a friend of mine's cat. The cat was facing amputation in one cancerous paw. My friend had been advised to use polysporin on it to stave off infection. I started researching essential oils safety for cats and entered the vortex...
The following is a work in progress. In short, I am still figuring it out. Please come back to this entry as I sift facts, collect my thoughts, and form opinions.
Why can essential oils be a problem for cats?
Cats are sensitive to essential oils for a few reasons.
1. Cats have very acute senses of smell.
2. Cats have delicate and thin skin, which allows for quicker absorption of these concentrated substances into the bloodstream.
3. Most importantly, cats can't efficiently metabolize some of the compounds in essential oils, which can lead to toxic build-up in their bodies.
Multitudes of cat owners have unknowingly used products with essential oils in their homes or directly on their pets! You are not alone.
What Essential Oils Can Harm Cats?
Here is a list of some essential oils that are known to be toxic to cats:
• Citrus oils
• Lavender (cheap perfume and camphorous types)
• Melaleuca (tea tree oil)
• Cinnamon (cassia)
• Any other oils containing phenols
Essential Oils should always be well diluted in a carrier oil or fat.
Cats are particularly sensitive to a group of oxygenated compounds called ketones and phenols, and some monoterpenes. It is the thujone content in ketones and carvacal in phenols that seem to create most of the problems when not used with enzymes. Carvacrol is a byproduct of d-limonene which is found in all citrus fruits and in many tree oils.
Examples of essential oils for cats that should be used with caution meaning highly diluted are shown below.
And just as with humans, each animal’s chemistry and blood type is different so the response is different!
Examples of oils containing Phenols – Wintergreen, Anise, Birch, Clove, Basil, Tarragon, Fennel, Oregano, Thyme, Mountain Savory, Peppermint, Tea Tree, Calamus, Cinnamon Bark, Citronella, Marjoram, Nutmeg, Eucalyptus citriodora, Parsley, Ylang Ylang. These all contain greater than 8% phenols.
Examples of oils containing Ketones – Western Red Cedar, Idaho Tansy, Marigold, Spearmint, Thuja, Hyssop, Davana, Sage, Dill, Yarrow, Peppermint. All these oils contain greater than 20% ketones.

Examples of Oils containing 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%.
