In this post, I’ll answer the question ‘Are essential oils safe for cats?’
Most essential oils are toxic to cats. This is due to cats having a different metabolism than humans.
There are a few exceptions and safe options that won’t cause any harm to your cat. Most times, essential oils are generally best avoided to keep your cat safe.
A lot of people believe essential oils are a good natural treatment for improving health.
However, many of these concentrated oils are toxic to cats.
Cats can suffer a range of problems from exposure to essential oils such as weakness, trembling, respiratory problems, and even death in extreme cases.
My name is Derrick and I write for Simply Cat Care. I am not a veterinarian and I recommend consulting with a vet if you are unsure about anything about essential oils. With that said, I spent some time researching this issue. I am going to share my findings in this article.

Which essential oils are toxic in cats?
Cats lack the liver enzymes needed to metabolize and eliminate essential oils .
Cats are not able to perform a liver process called glucuronidation. This is a process where the liver adds glycosidic bonds to help with drug excretion .
In basic terms, the liver needs to take chemicals and add/remove things so the body can get rid of them. Cats lack some processes to do this, so the chemicals build up.
As such, cats have a harder time disposing of toxins, especially phenolic compounds .
Since cats groom themselves, the topical application of essential oils results in an oral intake of oils .
Cats are very sensitive to phenols and phenolic compounds, found in a range of essential oils .
