Is Lavender Toxic to Cats?

I love lavender. I love the flowers, the scent, the color. I love everything about lavender, so imagine my delight when I recently won a gift bag full of lavender scented items. There was a lovely reed diffuser, body wash, moisturizer, even some laundry detergent.

Then someone said, “I hope you don’t have cats!” Oh, but I do. I have three cats. Then I had a little flicker in the back of my mind that reminded me I heard recently lavender is toxic to cats. So I put all those treasures away and didn’t think much more about them.

Then I also remembered that I have been using lavender scented air fresheners around my cats for years. What harm might I have done?

The end of June, I went to the BlogPaws pet blogging conference in Chandler, Arizona. BlogPaws and the Cat Writers’ Association joined forces this year to make the conference doubly awesome. We received swag bags loaded with lots of terrific items provided by the sponsors and vendors.

Over the weekend, I finally had some time to thoroughly go through the bags to see what was in them. I needed to decide what Christy Paws would give away on her blog for her birthday/gotcha day celebration.

One of the items included was a calming collar from Sentry. And there, right on the top, it said lavender and chamomile fragrance. Sentry is part of Sergeant’s Pet Care Products and I know Sergeant’s has had issues with their flea medications so immediately a red flag went up. I knew I had to do some research on lavender. I wanted to know, is lavender toxic to cats and if so, what exactly does that mean?

What Exactly Does Toxic Mean?

As with many things on the internet, you’ll find many opinions. I wasn’t interested in opinions. I wanted some facts. Even the ASPCA lists lavender as toxic to cats so there must be some merit to the claim. (When I look at the list of plants toxic to cats, I wonder how they ever survived!) So, the first thing I wanted to know is, what exactly does toxic mean?

Webster’s Dictionary defines toxic as “containing or being poisonous material especially when capable of causing death or serious debilitation.” Is this really true of lavender? Could it kill my cat? Some seem to say yes, don’t let it anywhere near your cat. It will destroy it’s liver. On the other end of the spectrum, an article in Catster says it is safe for your cats to eat.

Does a Plant Have to be Deadly to be Classified as Toxic?

This is where the confusion and varying opinions come in to play. The answer is a resounding NO! Plants don’t have to be deadly to be classified as toxic. Toxic can mean anything from a little will kill to a whole lot will cause an upset stomach. A “toxic plant” list tells you nothing about how much is dangerous.

Lavender falls into the “a whole lot will cause an upset stomach” category. Ingesting the plant or flowers may cause a mild GI upset with nausea and vomiting, according to the ASPCA. Moderation is the key and I think most cats are good at the moderation part on their own.

I wanted to know, is lavender toxic to cats? If it is classed as toxic to cats, what exactly does that mean? Is lavender safe to use around my cats? Check out this post for the answer to these questions and more.

What About Lavender Lotions and Diffusers?

But back to my goodies. I wasn’t planning on feeding lavender to my cats. I don’t even have a lavender plant. I want to use my room deodorizers and reed diffuser. I want to wear the lavender scented lotion. What about those? And what about that calming collar?

Dr. Melissa Shelton, who has pioneered the use of essential oils to treat animals, has used lavender (and other oils) in diffusers for years. When she first started, she watched her kitties closely and did lots of blood work to make sure they were healthy. She continued to monitor them to make sure no abnormalities were developing. Based on this and her observation of her cats’ behavior, she went on to explore further the use of essential oils for cats.

diffuserI feel pretty comfortable that my reed diffuser is fine to use around my cats. Of course, I have made sure they can’t get to it where they might ingest the oil and they can leave the room to get away from it.

If my cats don’t like the way something I have used smells, they let me know by moving away from me or it. It is unlikely that any hand or body lotion would contain enough lavender to create any kind of a problem but, to be safe, some recommend you wait until it is completely absorbed before touching your cat. I do that with any lotion anyway.

And as for that calming collar, according to the University of Maryland Medical Center, research has confirmed that lavender produces slight calming, soothing, and sedative effects when its scent is inhaled. Sentry says their collar uses “a pheromone that mimics the one mother cats produce to calm their kittens, the collars are clinically proven to reduce or eliminate stress-related behavior such as inappropriate marking, destructive behavior, clawing and anti-social behavior. Collars help alleviate problem behaviors triggered by travel, thunderstorms, fireworks and new social situations.”

The collar ingredients state pheromones (squalene) 6% and inert ingredients of 94%. There’s no mention of the lavender or chamomile so I called the company. They should be getting back to me in a day or two and I will update this post.

Once I hear from them, I might give the collar a try the next time I take Christy in the car. She doesn’t hate the car anymore but she sure doesn’t love it! If the collar could help her be more comfortable, that would be a good thing.

Please note that this post is about LAVENDER. There are other herbs, plants and oils that are detrimental and even deadly to cats. But remember, when you read that something is toxic, you really need more information than that.

Why the Concern Over Essential Oils?

Treating cats with essential oils is a totally different subject for another post, but I wanted to address, without going into detail, what the concern over essential oils is.

Essential oils are 500-2,000 times stronger than the flower or plant from which they came. A cat’s liver lacks the enzymes necessary to break down and excrete certain chemicals in many essential oils as well as other substances, like aspirin, and these chemicals can build up to a lethal level.

I want to leave you with this list from Optimum Choices of oils to definitely avoid around cats.

Lemon Lime
Orange Bergamot
Tangerine Pine
Mandarin Spruce
Grapefruit Fir
Cassia (cinnamon) Thyme
Clove Savory

I’d love to know about your experiences with lavender. Do you use it around your cats? Do you use essential oils?

  1. Hi, I am so glad I read your article. I also love lavender. I have a lavender scented candle that I usually light in my bedroom for relaxing sleep but I usually find my ginger boy has curled up and gone to sleep before me. Always when the candle is lit – even during the day!

    He also really enjoys my evening moisturiser which has a lavender scent. I have often woken up nose to nose with my cat after using the cream!

    I was concerned that Lavender was having an effect on the ginger boy but had concluded that it has a calming and soothing effect as it does on people. Fireworks are no longer a problem!!!
    Thank you !!

  2. I have a lavendar sachet in the cat toys and my cats pull it out and play with it. My cat is 2 now. So far no problems. He rubs his face all over it and pulls it out to play with a couple times a week. The girls are not very interested in the lavendar that I’ve seen. We all know kitties can be naughty at night while we sleep! Who knows what they do

  3. ASPCA lists lavender as toxic to cats.

    • Hi Carol. Thanks for stopping by and commenting. Yes, I mention that in the post. I went on to explain that what they mean by that with regard to lavender is that a whole lot will cause an upset stomach. In that sense it is toxic but not poisonous. There is a huge difference.

  4. I couldn’t figure out why my cat was suddenly having diarrhea, and then I noticed her nibbling on the new French lavender plant a friend gave me for my birthday. Which brought be here today. I’ve now moved it outside (cats are indoor only) and hoping she’s okay. She seems fine otherwise. Thank you!

    • Hi Ava! I’m just wondering if you ever heard back from Sentry regarding them not mentioning lavender or chamomile in their calming collar ingredients? I don’t see an update in your post yet. Would love an update!

  5. This is great information. I use essential oils for myself and always avoid them around my cats. I would love to diffuse lavender at bedtime, but was always afraid. It would sure help me sleep!

    • You really shouldn’t diffuse any essential oils around your cat. They are still inhaling them which can cause neurological damage. Please don’t use an oil diffuser if you have animals.

  6. Just wondering if you ever found out any more information on the calming collar from Sentry. I just put one on my cat today and I am really interested in hearing from anyone else who has used one. Thanks

  7. I never would have thought about Lavender being toxic to our pets. Thanks for bringing this to my attention.

  8. Thank you so much for this post! I didn’t know that lavender is toxic for cats!

  9. Thanks for reminding people how sensitive cats are and that toxic exposures can be cumulative. Great information! Citronella candles and oil are a problem for both cats and dogs. It’s that time of year for keeping mosquitoes at bay, whether you’re on an apartment balcony or in the yard. Thanks for helping people keep their pets safe =)

  10. Thank you for doing this research. This article was quite informative and I’m glad you’re able to use your goodies and not worry about harming your cats.

  11. This is great information to know about. I also have a cat and was wondering about lavender. Thanks for sharing this helpful information.

  12. Thanks for sharing this important info! I don’t have any cats but will pass this info to my sister in law

  13. Excellent and super informative post! I Pinned it on my “Mews News” Board!

  14. I had no idea about this! It makes me not want to use anything around my house or on me.

  15. I had no idea that lavender was considered toxic for cats, but I do agree that toxic doesn’t mean deadly. I think we feel toxic means it is deadly, glad you shared this to make it more aware to other cat owners. I am 34 and had no idea that this was the case for lavender.

  16. I’m glad to know that lavender is okay to use around cats. I think that a lot of us have fallen into the trap of thinking that reading that something is toxic and not finding out under what circumstances. I know that I’ve avoided giving my dogs avocado because I read it was toxic, but now I learned that the pit, skin, bark and leaves contain something that is toxic to birds and horses, while the avocado fruit is okay and healthy for dogs and cats to eat.

  17. So much great info. I am glad you clarified the definition of toxic. I always worry when I read articles stating a household product could be toxic to my fur babies.

  18. Wow I have to admit I had no idea about this! I don’t have a cat myself but my Mum does so I will be passing this straight onto her. x

  19. This is interesting! I have had cats my whole life and had no idea. We have 3 right now. I don’t like lavender so I don’t ever keep any of it around!

  20. I got married on a lavender farm, so suffice it to say I love myself some lavender. I’d be interested to see what a good friend of mine at pawcurious (and veterinarian) has to say on the topic. I’d never thought about lavender when it comes to cats (I don’t have one, but I’d love a Scottish Fold). Thanks for this info!

    • Hi Heather. I’d love to hear what your friend has to say if you get some info there. As much as I wanted facts, there still seems to be so many varying opinions on the topic. I love Scottish folds!

  21. Thanks for your research. I love lavender and have used it around my cats – diffuser like you. They are similar to your cats and move away from smells they don’t like. I also have always been a bit uneasy about using essential oils with my pets – glad to have this list of the ones to absolutely avoid.

  22. I really appreciated your information about what toxic really means. I’ve always thought that a pet had to ingest it in order for it to be toxic, but you’ve brought up a great point about fragrances! So many things that we do without thinking that can really affect our pets!!

  23. Oh wow, this really surprised me. I don’t have cats, I’ve got two dogs. I hope lavender isn’t toxic to them, I grow it in my yard! They haven’t munched it, but I need to look into whether it may need to be moved to the front or if it’s safe in case they decide to snack on it. Thanks for this info!
    Love & Biscuits,
    Dogs Luv Us and We Luv Them

    • Dogs are far less sensitive than cats and lavender is considered safe for dogs. Over-indulging, as with anything, can sometimes cause reactions in some dogs.

  24. I don’t have a cat anymore, but I remember having to be careful what the cat would get into. This is great information for a cat owner.

  25. Wow I never would have know. This post is very informative thank you so much for sharing.

  26. I Never Gave It Much Thought Til Now I Have Cats Never Had A Issue That I’m Aware Of With Lavender.I Thought Toxic Mean’t Deadly Til I Read Your Article Thank You For Making Me Aware Of This & All Your AWESOME Information!

  27. Interesting. I must admit I was surprised how many plants and products can be toxic for cats and dogs if they ingest them.

  28. I sometimes wonder the same thing! It seems like a lot of things are toxic for cats.

  29. What a great read, thank you! I didn’t know that about lavender, and I also like the scent. But I guess it’s okay to continue enjoying the scent around cats.
