Essential Oils & Your Pets | Q&A

We love using essential oils here at the CMS HQ to add a little zing to our DIY cleaning products—they not only smell great, but many of them also have unique anti-microbial and anti-bacterial qualities which make them Ideal for this. Cheryl asks:

I love essential oils too, but I keep reading that they are a no-no if you have cats. I see that your two beautiful cats seem perfectly fine and that you use essential oils all the time. Can you clarify if there are rules you need to follow if you have pets?

Melissa Says:

Indeed, a number of oils are known to be toxic to animals, including, unfortunately, some of my favorites! Cinnamon, clove, wintergreen, and tea tree are among the ones that can be toxic to cats (there are a few more not listed here, as well as different ones for different animals—do your research!). Still, with some precautions, you can have both pets and essential oils in your life.

First off, if you want to use a diffuser: Your house should never be overpowered with a scent. Cats and dogs have a much stronger sense of smell than we do, and they can become overwhelmed easily. If you diffuse, be sure it’s in a small space, and that the rest of the house is kept scent-free so that the pet can retreat to another room. You can even consider keeping that area off-limits for pets during the diffusing session. Second, be sure that your diffuser is 100% spill-proof since you don’t ever want your pets coming directly in contact with the oils within.

As far as cleaning with essential oils, using a few drops mixed in with a lot of water (and any other ingredients) as a cleaning solution is very much diluted, so it shouldn’t cause any trouble for the cats. I still use eucalyptus in my floor cleaner.

Still, I recommend talking to your vet and learning about any symptoms to watch for. As long as your cat seems happy and healthy, you’re probably striking just the right balance!

Good luck!

  1. Thanks for addressing this issue. I’ve been concerned about it since I like to use essential oils in my DIY cleaners and room deodorizers. To play it safe, I’m just avoiding spray diffusers altogether! (My husband is sensitive to aromatics anyway).
