My cat was exposed to essential oils. What are the signs of harm?

Updated on September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 16.6 lbs

Hi, I was browsing online for recipes to make air fresheners using essential oils. One site included a list of oils that are potentially hazardous to cats. I did some research and I learned that cats are unable to metabolize essential oils due to the lack of glucuronyl transferase, a liver enzyme. I've been using essential oils in air diffusers, laundry detergents, homemade cleaning supplies and more. I am so worried now. How can I tell if my cat has been harmed by the oils?

You're right that cats can be very sensitive to essential oils, so it's always recommended to be very cautious when using these oils around them.

If Odie is acting normal (eating and drinking, active, etc.), it's unlikely that he would have been negatively affected by any essential oils that you may have used in the past. You could take him to your vet for a check-up and blood work to check his liver and kidney function, if you want to be absolutely sure - but if he's clinically doing fine, he's probably okay :)

In the future, it would be best to double-check the safety of any oil you are considering for use in your home to avoid problems.
