Is Eucalyptus Toxic to Cats and Dogs?
Yes, eucalyptus is toxic to both cats and dogs. That applies to the living plant, cut stems, dried leaves and the popular eucalyptus shower bundles hanging in bathrooms everywhere.
The main problem is a compound called eucalyptol. It is what gives eucalyptus its fresh, spa-like smell, and it is also what can make your pet sick.
Below you will find what happens if your pet eats eucalyptus, why bathroom bundles are a hidden risk, and pet-safe swaps that give you a similar look.
The Short Version
- Eucalyptus is toxic to both cats and dogs, fresh, dried or as an oil.
- The toxic compound is eucalyptol, a natural oil that pets cannot process well.
- Common symptoms: drooling, vomiting, diarrhea, weakness and low energy.
- Dried shower bundles stay toxic, and steam can spread the oils into the air.
- Essential oil diffusers with eucalyptus are also a risk in a pet household.
- Safe decor swaps exist, such as dried wheat, oat stems or pet-safe greenery.
- Call your vet or a pet poison hotline if your pet chews eucalyptus and shows symptoms.
Why Eucalyptus Is Toxic to Pets
Eucalyptus contains eucalyptol, also called cineole. It is a concentrated plant oil that smells wonderful to us but is hard on pets.
Dogs and cats break down certain plant compounds far less efficiently than humans do. Eucalyptol is one of them. When a pet chews the leaves or drinks water that eucalyptus stems have sat in, the oil can irritate the stomach and affect the nervous system.
Cats are especially sensitive. Their livers lack some of the enzymes needed to process these oils, so even small amounts can cause problems.
This is similar to other aromatic plants. If you have read our guide on whether lavender is toxic to pets, the pattern will look familiar: a lovely scent for you, a real risk for them.
Symptoms of Eucalyptus Poisoning in Cats and Dogs
Symptoms usually show up within a few hours of chewing or swallowing eucalyptus. Watch for:
Drooling and pawing at the mouth
Vomiting and diarrhea
Weakness, wobbliness or unusual tiredness
Loss of appetite
In heavier exposures, depression or a low body temperature
Most cases from a quick nibble of a leaf stay mild. But concentrated oil, either from a bottle or a diffuser, can cause much stronger reactions even in small amounts.
If your pet shows any of these symptoms after contact with eucalyptus, call your vet. Do not wait to see if it passes on its own.
The Hidden Risk: Dried Eucalyptus Shower Bundles
Hanging a eucalyptus bundle in the shower is one of the biggest decor trends of the past few years. It looks great and smells even better. It is also easy to forget about, because it feels like decoration rather than a plant.
Here is the problem. Drying does not remove eucalyptol. Dried leaves are still toxic if chewed.
Steam makes it worse. Hot water releases the oils from the leaves into the air and lets droplets collect on the floor and walls of the shower. A cat that walks through a wet bathroom and licks its paws, or a dog that licks the floor, can take in small amounts of the oil.
Bundles also shed. Dried leaves drop to the floor over time, right at nose and paw level. Curious pets and fallen leaves are a bad combination.
If you love the look, the safest option is to swap the bundle for a pet-safe alternative and keep any eucalyptus oil products in a closed cabinet.
Quick action
What to Do if Your Pet Eats Eucalyptus
Remove access
Take the plant, bundle or oil away and pick up any fallen leaves. Check your pet's mouth for leftover pieces.
Check for symptoms
Look for drooling, vomiting, diarrhea or weakness. Note what your pet chewed and roughly how much.
Call your vet
Describe the plant and the symptoms. You can also call the ASPCA Animal Poison Control Center or the Pet Poison Helpline. A fee may apply.
Do not induce vomiting yourself
Only do this if a vet explicitly tells you to. With oil-based toxins, vomiting can sometimes cause more harm.
Follow up
Watch your pet for the next 24 hours and follow your vet's instructions. Most mild cases resolve well with prompt care.
| If you wanted | Pet-safe swap | Why it works |
|---|---|---|
| Dried shower bundle | Dried wheat or oat stems | Similar tall, airy look, generally considered non-toxic, no oils released by steam |
| Fresh eucalyptus stems in a vase | Eucalyptus-free greenery like a parlor palm or Boston fern | Soft, drapey green texture, safe around cats and dogs |
| Eucalyptus scent in the bathroom | Good ventilation or an unscented candle kept out of reach | Fresh feeling without airborne plant oils |
| Eucalyptus centerpiece | A pet-safe bouquet from a local florist | Ask for arrangements without eucalyptus, lilies or tulips |
| Silver-green foliage plant | Calathea or peperomia | Silvery, patterned leaves that handle indoor light well |

A Note on Essential Oils and Diffusers
Eucalyptus essential oil is the most concentrated form of eucalyptol. A knocked-over bottle, a spill on fur or skin, or a diffuser running in a small closed room can all expose your pet.
Cats groom themselves constantly, so oil particles settling on their coat end up being swallowed. Birds and small pets are even more sensitive to airborne oils.
The practical rule: in a home with cats or dogs, skip eucalyptus oil entirely. There is no safe way to make it pet-proof once it is in the air.

Other Trendy Plants Worth Checking
Eucalyptus is not the only popular plant with a toxic streak. Many Instagram favorites, like pothos and philodendron, also cause mouth irritation and stomach upset in cats and dogs.
The good news: for almost every toxic plant, there is a pet-safe alternative with a similar look and light level. That is exactly what we do at Pawproof Plants.
Frequently Asked Questions
Is eucalyptus toxic to cats?
Yes. Eucalyptus is toxic to cats, fresh or dried. Cats are especially sensitive to eucalyptol because their livers process these oils poorly. Symptoms include drooling, vomiting, diarrhea and weakness. Call your vet if your cat chews any part of the plant.
Is eucalyptus toxic to dogs?
Yes, it is toxic to dogs too. Dogs that chew the leaves or drink vase water with eucalyptus stems in it can develop vomiting, diarrhea, drooling and weakness. Contact your vet if symptoms appear.
Are dried eucalyptus shower bundles safe for pets?
No. Drying does not remove the toxic oils, and steam from the shower releases eucalyptol into the air and onto wet surfaces. Fallen dried leaves are also a chewing risk. Choose a pet-safe swap like dried wheat instead.
Is eucalyptus essential oil dangerous for pets?
Yes. Essential oil is the most concentrated form of eucalyptol. Diffusers, spills and skin contact can all expose pets, and cats are at extra risk because they groom oil particles off their fur. In a pet household, it is safest to skip eucalyptus oil altogether.
What happens if my cat or dog eats a small piece of eucalyptus?
A small nibble often causes mild symptoms like drooling or an upset stomach, but even small amounts can be a problem for cats. Remove the plant, watch your pet and call your vet for advice, especially if vomiting, diarrhea or weakness appear.
What can I hang in my shower instead of eucalyptus?
Dried wheat or oat stems give a similar airy, natural look without the toxic oils. They are generally considered non-toxic, though any plant material is best kept where your pet cannot chew it regularly.
