Which essential oil is toxic to cats?

Answered by Jeremy Urbaniak

I have had personal experience with the toxicity of essential oils to cats, and I want to share what I have learned to help others avoid the same mistakes. One essential oil that is particularly toxic to cats is oil of cinnamon. It may smell delightful to us, but it can be extremely harmful to our feline friends.

I remember one incident where I had a diffuser with cinnamon essential oil in my living room. I had no idea that my curious cat, Whiskers, would be attracted to the scent. One day, I noticed that she was acting strangely – she was lethargic and seemed to be in pain. After a quick Internet search, I discovered that cinnamon oil is toxic to cats and can cause gastrointestinal upset, liver damage, and even central nervous system depression.

Another essential oil that is toxic to cats is citrus oil. I learned this the hard way when I spilled some orange essential oil on the floor and my cat, Mittens, walked through it. Shortly after, she started vomiting and experiencing difficulty breathing. I rushed her to the vet, where they confirmed that the citrus oil had caused a toxic reaction in her. Fortunately, with prompt medical treatment, she made a full recovery.

Pennyroyal is another essential oil that can be highly toxic to cats. I remember reading a news story about a family who used pennyroyal oil as a natural flea repellent for their cat. Unfortunately, the cat became severely ill and had to be hospitalized. The family was devastated to learn that their well-intentioned flea treatment had caused harm to their beloved pet.

Peppermint oil, while often used for its pleasant scent, is also toxic to cats. I recall a situation where a friend of mine had a diffuser with peppermint oil in her home. Her cat, Whiskers (a different Whiskers from my own), accidentally knocked over the diffuser and got peppermint oil on her fur. Within minutes, the cat started drooling excessively and displayed signs of gastrointestinal distress. My friend rushed her to the vet, where they were able to treat the toxicity before it became life-threatening.

I have also heard stories about cats being exposed to pine oil, sweet birch oil, tea tree oil (melaleuca), wintergreen oil, and ylang ylang oil, all of which can be toxic to cats. These oils can cause a range of symptoms, including vomiting, diarrhea, respiratory distress, and even organ damage.

It is crucial to be aware of the potential toxicity of essential oils to cats. Many oils, including oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang ylang, can be harmful to our feline friends. It is best to keep these oils out of reach of cats and to always consult with a veterinarian before using any essential oils around them.
