Is Cedar Oil Toxic to Cats?

Cats are special to us here at Cedarcide. They work alongside us all day, everyday—sleeping in our laps, lounging on our desks, watching over us as we hand-bottle and package your orders.

Occasionally we’re asked, “Is cedar oil toxic to cats?” The short answer is No. We wouldn’t let our furry friends hang around—much less use—our products if they were unsafe for cats. But there’s more to be said about the relationship between cedar oil and cats. Let us explain.

Cats, which are highly sensitive to odors and many essential oils, can suffer adverse side effects from improperly formulated cedar oil. Phenols, which are naturally present in several essential oils, can be outright fatal to cats, especially smaller individuals such as kittens. An inability to metabolize this common ingredient is what renders some types of cedar oil harmful to cats. Furthermore, some species of cedar—like Western red cedar—are naturally toxic to both pets and people, and should never be used in topical pet products.

Firstly, Cedarcide cedar oil never contains phenols or phenolic compounds. Secondly, because we use only the highest quality cedar oil sourced from only pet-safe cedar trees (Juniperus ashei, to be specific), our products are always non-toxic, all natural, and safe for pets. Using a multi-step filtration process, our cedar oil is purified of all unnecessary contaminants—including any potentially harmful ingredients like phenols.
However, as with any topical pet product, you should test your cat for possible sensitivity or allergy to cedar oil with a small initial application.

At Cedarcide, we offer two main products for cats and cat owners: our family-safe insecticide and repellent, Cedarcide Original, and our new Flea + Tick Brush.  


Because cats like to lick their fur, and because they’re also extremely sensitive to scents, it’s best to test for possible sensitivity with a light initial application. While Cedarcide Original is non-toxic and cat-safe, on rare occasions smaller cats and kittens have found the natural cedar scent of Cedarcide Original too strong for their liking.

If like most cats, your furry friend has no issue with Cedarcide Original, apply the formula by lightly misting your hands and massaging the spray into your cat’s coat. Apply Cedarcide Original all over—including armpits, in between toes, and around the ears and tail. Using Cedarcide Original in this way will not only kill any hidden pests, it will also provide protection against additional fleas, ticks, mosquitoes and other biting insects.


The Cedarcide Flea + Tick Brush is the safest, easiest and most effective way to protect your cat from fleas, ticks and other biting insects. Designed to dispense Cedarcide Original directly to your pet’s skin, the Flea + Tick Brush takes the mess out of keeping your cat safe from harmful pests.

    I have a carpet beetle larvae problem, I was told that cedar oil would kill them but i also need it to be safe for my cats. Do you know if yours would work for that or have you done something to yours that has made it non lethal to them?

      Hi there, Frankee.

      Our products are very popular for carpet beetles and pet-safe 🙂

      I’d suggest this: https://www.cedarcide.com/product/all-purpose-bug-spray/

    In the UK, I can only find cedarcide original for dogs via Amazon

    My friend has a disabled cat and last year the dreaded flystrike happened.

    Is this product cat friendly and will it help prevent it this summer? My friend does a lot of rescue work with older and wonky cats so we need to be confident that we buy the right product

    Many thanks! Angie

      Great question. Yes, Cedarcide Original can also be used for cats and has been for over 20 years 🙂

      Just apply using your hands every 4–5 days, it will kill bugs on contact and then help biting bugs after that.

      I’m here if you need anything else.

  3. Can I use Cedarcide in my cat’s ears for ear mites?

    1. Jonathan At Cedarcide

      Hi there! You can dip a swab or cotton ball in Cedarcide Original and apply it to the ear that way, just don’t get real deep as Cedarcide Original is not external use 🙂

  4. Would this be safe for use on a week old kitten?

    1. Jonathan At Cedarcide

      Sure will, just apply lightly using your hands 🙂

  5. Do you, or would you possibly in the future, sell cedar cat litter?

    1. Jonathan At Cedarcide

      Hi, Sharon, great question!

      We do not currently sell cedar cat litter nor do we suspect we will anytime soon. Raw cedar chips, while cat-safe to use around the home or yard, is not suggested for use as litter, as some cats can be sensitive to the aroma of raw cedar trees, and using it for their litter will put them in unavoidable contact with it on a regular basis. Let us know if you have any more questions, we’re always here 🙂

      1. Cats lick after its applied so it seems like they’re taking it back off. What do you recommend?

        1. Jonathan At Cedarcide

          Hi, Suzannae!

          This little bit of removal should not decrease the products’ efficacy 🙂
