One night, I was enjoying my diffuser, completely unaware of the dangers and assuming it was eucalyptus safe for cats and dogs.
I thought it was calming until my cat started drooling and hiding the next morning.
I didn’t know eucalyptus was toxic. That changed everything. What’s safe for us isn’t always safe for pets.
Eucalyptus can harm cats and dogs. In this guide, I’ll share whether eucalyptus is safe for cats or not!
What is Eucalyptus?
Eucalyptus sounds so healthy, right? You find that in medicine, aromatherapy, and many household products.
The leaves contain a clean, spa-like scent, which is used in oils, balms, and even shower sprays.
It is mostly found in Australia. It is the main food source for koala bears.
This oil is a combination of both antiseptic and anti-inflammatory properties.

Common Uses of Eucalyptus in Homes
You already have eucalyptus somewhere in your home without even realising it, right?
For me, it started with essential oil in a diffuser, cleaning sprays, and even the dried eucalyptus in my bathroom.
It smells amazing and feels refreshing. But that’s exactly how the risk sneaks in.
Diffused oils and sprays, and even a fresh eucalyptus bundle hanging in the shower, can release oils into the air.
It’s not about throwing everything out, but about becoming aware of where eucalyptus is hiding so we can make safer choices for our pets.

How Eucalyptus Affects Cats
I noticed my cat suddenly started vomiting and drooling after I’d used a eucalyptus diffuser all night.
I was terrified to learn that cats can’t process essential oils the way humans can.
Their livers lack the enzymes that are needed to break down certain plant compounds, especially those found in eucalyptus oil.
Even small amounts can build up and cause toxic reactions, and eucalyptus is not that safe for cats.
Symptoms can include everything from lethargy and wobbling to difficulty breathing.
And here’s the scariest part? Cats often suffer in silence. They won’t always meow or cry, they’ll just quietly hide.
That’s why it’s necessary to avoid using eucalyptus products in rooms where your cat sleeps or eats. The risk just isn’t worth it.

How Eucalyptus Affects Dogs
Dogs may seem a bit stronger than cats when it comes to smells, but eucalyptus can still be dangerous for them, too.
I once sprayed eucalyptus room freshener near my dog’s bed, and within an hour, I noticed vomiting and feeling uncomfortable.
That was the last time I made that mistake. Dogs can be affected by eucalyptus through skin contact, inhalation, or ingestion.
Since dogs explore everything with their noses and mouths, even a drop of oil on their fur or paws can make them sick.
They may drool, tremble, or have trouble breathing. If your dog’s behaviour changes after using eucalyptus, don’t wait, call the vet right away.

Signs of Eucalyptus Poisoning in Pets
What is the worst moment for any pet parent? I think seeing your pet in distress and not knowing why.
That happened to me when my cat started trembling and vomiting after I’d used eucalyptus oil near her litter box.
I didn’t know the risk and thought about eucalyptus until my vet asked, Have you used any essential oils recently?
The signs of eucalyptus poisoning can be severe, like drooling, vomiting, diarrhoea, unsteadiness, weakness, and breathing trouble.
In cats, excessive grooming or hiding can also be a red flag. When it comes to eucalyptus, it’s better to overreact than overlook.
If you notice anything unusual after using a diffuser or spray, stop everything, remove your pet from the area, and call your vet.

Are Eucalyptus Essential Oils Safe for Pets?
Essential oils feel magical. I used to love diffusing eucalyptus during a bath or at bedtime.
But I learnt that essential oils, especially eucalyptus, are highly concentrated and too strong for pets.
They can’t metabolise these oils like we do. Even diluted, vapours can also irritate their breathing.
If they lick the oil on the floor, furniture, or their fur, it can make them very sick.
So now, I either avoid essential oils altogether or use extremely diluted, pet-safe alternatives.
Don’t use in pet rooms. The benefit of a nice scent is never worth risking their life.
Using Eucalyptus Diffusers Around Cats and Dogs
I know how it feels to walk into a room that smells like eucalyptus. I loved that calming spa vibe.
But once I learnt how diffusers could quietly affect my pets, I couldn’t look at them the same way.
When essential oils like eucalyptus are diffused, tiny particles fill the air. We might enjoy that, but our pets breathe those constantly.
Cats can’t clear those toxins from their bodies. Even dogs, if exposed for too long, can show signs of distress.
If you want to use a diffuser, do it in a pet-free, well-ventilated space, and limit the time it’s on.
I stopped using eucalyptus altogether. That peace of mind is so much more soothing.
Safe Alternatives to Eucalyptus for Pet Owners
Once I decided to stop using eucalyptus products, I worried I’d lose the vibes it brought.
But I found gentler, pet-safe alternatives that still make my home smell great.
First, I started using lavender oil just a little bit, super diluted. It helps me relax without affecting my pets.
Chamomile is another soft, safe option, great for calming stress in both humans and animals.
Even better? Naturally dried herbs like rosemary or mint are tied in sachets or hung in the shower. They give a fresh scent with zero risk.
It’s not about giving up nice smells, it’s about finding a safer way to enjoy them. You and your pets deserve a home that feels good and safe.

What to Do if Your Pet is Exposed to Eucalyptus
If your pet gets into eucalyptus oil, leaves, or even vapour, don’t wait, you have to react immediately.
First, move your pet away from the scent or source. Turn off the diffuser, open windows, and let fresh air in.
Don’t try to make them vomit instead; call your vet or a pet poison helpline.
Explain exactly what your pet was exposed to, and how much they’ll guide you on what to do next.
Keep the product’s label or packaging handy, it helps your vet assess the situation quickly.
The sooner you act, the better your pet’s chance at a full recovery. Time is everything.

Tips for Pet-Proofing Your Home from Essential Oil Hazards
Before exploring the facts about whether eucalyptus is safe for cats, I used to think my home was safe until I realised how many products were harmful to my pets.
One day, I caught my dog sniffing around a tipped-over bottle of eucalyptus oil on the shelf. My stomach dropped.
After that, I started to place every oil bottle in a high area and seal it tightly.
Diffusers should be used only when your pets are out of the room, and always ventilate well.
Even stop using certain cleaning sprays that had hidden eucalyptus oil in them.
Pet-proofing your space isn’t just about what you see, it’s about thinking like your pet.
It’s time to follow these little changes to get a safer environment for you and for your pets.
