What Flowers Are Toxic to Cats?
Find out what you can and can’t plant in your garden.
If you have a green thumb, you might imagine your cat joining you in your garden, sniffing the roses and jumping from flower bed to flower bed (just don’t let them do their business there). But can plant parenthood happily coexist with pet parenthood? Cats aren’t always kind to plants and can be destructive towards them (along with many other items in your home). But some flowers can pose a threat to felines, too.
A number of flowers can in fact be poisonous to cats, causing anywhere from mild to severe symptoms if consumed. Some, even, can be deadly to cats. So when you’re buying seeds and choosing which flowers to populate your garden come spring, you’ll want to be aware of which plants are cat-safe and which should be avoided.
One variety of flower in particular is both beautiful and dangerous, and that’s flowers belonging to the lily family. These plants can cause acute and potentially fatal kidney failure in cats, and it can happen quickly, through simply licking pollen from the petals — not even ingesting the flower, stems, or roots. Be sure to avoid lilies in your household, and steer clear of other flowers containing potentially dangerous toxins, including:
Daffodils, which contains the poisonous agent lycorine
Autumn crocuses
Azaleas
Rhododendrons
Hyacinths
Oleanders
Why are some flowers dangerous for cats?
Some plants are highly toxic to cats, while others don’t present any threat at all. Many plants cause mild side effects, like gastrointestinal symptoms (vomiting or diarrhea) or irritation to the mouth and tongue. However, other plants contain toxins that are life-threatening, causing heart problems, difficulty breathing, seizures, or damage to organs like the liver and kidneys.
How much do you spend on your pet per year?
“There are numerous plants and flowers that are potentially toxic to cats,” Dr. Amy Fox says. “Lilies are one of the most infamous flowers that are toxic to cats, as they can cause potentially fatal kidney failure if consumed.” In 2025, the ASPCA Poison Control estimatedopens in new tab that 7.5 percent of all calls to the center came from plant exposures.
What should I do if my cat has eaten a toxic flower?
If you suspect your cat has consumed a toxic flower, contact your vet immediately or visit an emergency vet clinic. You can also call an animal poison control helpline, like the ASPCA Poison Control Centeropens in new tab at 888-426-4435 or the Pet Poison Helplineopens in new tab at 855-764-7661.
When you head to the vet, make sure to bring along samples or photos of the plant if possible and be prepared to provide information about the type of plant, how much your cat ingested, and how long it’s been since they ate the flower.
Diagnosing plant poisoning in cats
The more information you can provide to your vet about the plant your cat consumed, the quicker they can reach a diagnosis and start treatment. If you aren’t able to provide any details, the vet will have to run a series of tests to determine what type of poison your cat was exposed to and develop a treatment plan.
Symptoms of plant poisoning in cats
If you have toxic plants in the home, be aware of the symptoms of plant poisoning. Contact your vet immediately if you notice your cat has any of these symptoms:
Vomiting or diarrhea
Abdominal pain
Drooling
Lethargy
Loss of appetite
Mouth or tongue irritation
Difficulty swallowing
Tremors or seizures
Treatment
The treatment your vet decides on will depend on how serious the case of poisoning is for your cat. Your vet may suggest hospitalization for more serious cases, while more mild cases may involve treating your cat for nausea or diarrhea.
How to prevent plant poisoning
To keep your cat from ingesting a toxic flower, find ways to keep potentially poisonous plants out of their reach. Try elevating plants, whether in hanging planters or in large containers or planters that can keep your cat from accessing the flower itself. Take the time to learn about which plants are toxic to your cat so you can more easily identify — and avoid — them.
“Pet parents should always do their research about a specific plant they are considering bringing into their home to learn about risks of toxicity to their pets,” Dr. Fox says. “The ASPCA poisonous plant database onlineopens in new tab is a great resource to learn about thousands of plants and their safety and toxicity profiles.”
If you do have unsafe plants in your home, think about the best place to put them to keep your cat away. Remember that cats are able to jump and climb, so simply setting a plant on a shelf often won’t be good enough.
Are all parts of a toxic flower poisonous to cats?
Some plants are poisonous to cats regardless of which part they eat, while others may contain toxins only in specific parts, like the bulbs, leaves, or flowers. Make sure to know which plants present a danger to your cat and which are safe to have around the house or garden.
How do I stop my cat from eating toxic flowers?
The best way to keep your cat from eating poisonous flowers is to keep them out of your home entirely. At the very least, keep toxic plants out of your pet’s reach by using hanging planters or keeping them in a room with a door you can close. If your cat goes outside, make sure they do so supervised, preferably on a leash or harness, or make use of a catio. Be sure to research any plant you want to add to your home or garden to determine if it’s safe for your cat to be around.

FAQs
What happens if my cat eats a toxic flower?
It depends on the type of flower your cat consumes, but a toxic plant could result in mild to severe symptoms, such as vomiting, diarrhea, or even difficulty breathing.
Are toxic flowers poisonous to cats if they smell them?
Most toxic flowers are not poisonous to cats if they simply smell them, but it’s best to keep any poisonous plants out of your cat’s reach. However, highly toxic flowers, like lilies, can make cats sick even if they smell them. This is likely because they get pollen on their nose that they then lick and ingest and this can make them very sick. Highly toxic flowers should not be within sniffing range of cats.
