What flowers are toxic to cats?
The most toxic flowers for cats are true lilies and daylilies, which can cause fatal kidney failure from a single leaf, petal or lick of pollen. Other dangerous flowers include tulips, daffodils, azaleas, oleander, lily of the valley, autumn crocus, cyclamen, hydrangeas, chrysanthemums and amaryllis. Carnations, baby’s breath and peonies are mildly toxic.
- 🔴 Deadly: lilies (Lilium), daylilies, sago palm, oleander, lily of the valley, autumn crocus
- 🟠 Toxic: tulips, daffodils, hyacinths, azaleas, cyclamen, hydrangeas, amaryllis, mums
- 🟡 Mild stomach upset: carnations, baby’s breath, peonies, daisies, lavender, poinsettia
- 🟢 Safe: roses, sunflowers, orchids, gerbera daisies, snapdragons, freesia, zinnias, asters
Cats are more sensitive than dogs to many plant toxins, and they groom pollen and sap off their fur. As a vet, I tell owners one rule above all others: no lilies in a home with a cat, ever. Everything else on this page helps you choose flowers you can enjoy safely.
Below you’ll find pictures of the 10 most dangerous plants and 10 safe flowers, an A–Z safety chart, answers for the flowers people ask about most, and exactly what to do if your cat eats one. If you need help right now, call a poison control line or your vet.
Which flowers are safe for cats?
Flowers that are safe for cats include roses, sunflowers, orchids, gerbera daisies, snapdragons, freesia, zinnias, asters, alstroemeria, lisianthus, statice, petunias, African violets and camellias. They appear as non-toxic on the ASPCA plant list and in PetMD’s vet-reviewed guide.
“Safe” means the plant contains no known toxin for cats. It doesn’t mean your cat should eat it. Any plant eaten in quantity can cause vomiting or diarrhea, and roses have prickles that can poke a curious nose or paw.
When you buy or receive flowers, check every stem in the arrangement, not just the main flower. A bunch of roses can hide a sprig of baby’s breath or a single lily. Ask your florist for a cat-safe arrangement and remove the packet of flower food.
If your cat loves to chew greenery, give her something she’s allowed to eat. A pot of oat or wheat grass often satisfies the urge and keeps her away from your bouquet. The PetMD guide calls grass grown for cats the safest plant you can own.
Pictures: 10 of the most toxic plants for cats
These are the 10 flowering plants I’d most want every cat owner to recognize, ranked by how dangerous they are. Use the illustrations to get the idea of each plant, then check the label or ask your garden center when you’re unsure.
Several of these, including oleander, lily of the valley and kalanchoe, contain cardiac glycosides that can disturb the heart. Azaleas, autumn crocus and sago palm can cause severe illness, convulsions or organ failure even in small amounts.
Pictures: 10 flowers that are safe for cats
These 10 flowers are listed as non-toxic for cats, so they’re good choices for your home, garden and gift bouquets. They may still cause a little stomach upset if a cat eats a lot of them.
Other safe choices include asters, alstroemeria, lisianthus, statice and the Christmas cactus. Garden favorites like petunias and zinnias are safe in beds where outdoor cats roam.

Why are lilies so dangerous for cats?
Lilies are the most dangerous flowers for cats because every part, including the petals, leaves, pollen and even the water in the vase, can cause sudden kidney failure. There’s no known safe amount.
True lilies (Lilium) include Easter, tiger, Asiatic, Japanese and Oriental lilies, while daylilies are a separate genus with the same effect. A cat that brushes past a bouquet and licks pollen from her fur can be poisoned. The toxin hasn’t been identified, and it doesn’t affect dogs the same way.
Signs start with vomiting, drooling, hiding and not eating within hours. Then, over 24–72 hours, the kidneys fail: she may start drinking more and urinating more, then stop urinating entirely. Without treatment, acute kidney injury from lilies is often fatal.
Treatment works best when started early. Vets make her vomit to remove the plant, give activated charcoal and run intravenous fluids for about 48 hours while monitoring kidney values. Never wait for symptoms after any lily exposure.
Lily season peaks around Easter, Mother’s Day and the holidays. Check every flower delivery before it enters the house.
Are roses toxic to cats?
No, roses are not toxic to cats. The ASPCA lists roses as non-toxic, so the petals, leaves and hips won’t poison a cat that nibbles them.
The real risk is the thorns. A curious cat can get a thorn stuck in her paw, lip or tongue, and a deep jab can become infected. Florist roses are usually de-thorned, but garden roses aren’t. If she’s limping or pawing at her mouth after investigating a rose, look for a splinter or swelling and call your vet if it doesn’t settle.
Chemicals are the other concern. Commercially grown roses may be sprayed with insecticides or fungicides, and garden roses may be treated with systemic products. Rinse bouquets before display, and don’t let your cat chew garden roses you’ve treated.
Miniature roses, white, red, pink and yellow roses all carry the same verdict: safe. That makes roses the best choice for Valentine’s bouquets in a cat home, as long as nothing else in the arrangement is toxic.
Are tulips toxic to cats?
Yes, tulips are toxic to cats. The whole plant contains irritant compounds, but the bulb has the highest concentration. Most cats that nibble a petal or leaf get only drooling, vomiting or diarrhea.
Cut tulips in a vase usually cause mild stomach upset if chewed. The bigger danger is a bulb: a cat that chews on one, whether stored in the garage or in a pot, can get more severe vomiting, diarrhea, a fast heart rate and breathing changes.
Tulips are among the most common flowers in late-winter and early-season bouquets, so they come into homes often. Keep vases out of reach, and store any bulb you plan to plant in a closed container.
Outdoors, protect newly planted beds with chicken wire if your cat likes digging, and choose cat-safe alternatives near the back door. If your cat chews a tulip bulb, call your vet or a poison line.
Are carnations toxic to cats?
Yes, carnations are mildly toxic to cats, usually causing mild vomiting, diarrhea, or redness and itching where the sap touched her skin. Serious poisoning is very unlikely.
The ASPCA lists carnations as toxic, but the effects are minor and short-lived. The toxin isn’t known, though experts suspect irritant saponins similar to those in baby’s breath, a close cousin. Most cats recover at home within a day.
Carnations are popular in supermarket bouquets, Mother’s Day bunches and funeral arrangements, often mixed with baby’s breath. If your cat chews one, wipe her mouth, offer fresh water and watch for repeated vomiting.
Call your vet if she stops eating, vomits more than twice, or has a red, swollen mouth or paws. For a gift bouquet, roses, sunflowers or gerbera daisies are cat-safe swaps with a similar look.
Are orchids toxic to cats?
No, orchids are not toxic to cats. The Phalaenopsis orchids sold in supermarkets and garden centers are listed as non-toxic by the ASPCA, and they’re one of the best flowering plants for cat homes.
Other common orchids, including Cymbidium and Dendrobium, are also generally considered safe. That makes orchids a great swap for lilies as a gift plant.
Two minor cautions: chewing a lot of leaves can still upset the stomach, and orchid potting media and fertilizer can cause digestive upset if she digs and eats it. Some cats also like knocking pots over, so use a heavy pot.
Keep orchids on a high shelf or in macramé holders if your cat is a plant chewer. They bloom for weeks with little care, so they’re ideal for busy owners who still want flowers.
Is lavender safe for cats?
No, lavender is not completely safe for cats: the ASPCA lists it as toxic, mainly causing nausea and vomiting if eaten. A sniff or brush past a garden plant isn’t dangerous.
The plant contains compounds that cats can’t break down well. Eating a few leaves or flowers can cause drooling, vomiting and loss of appetite. The concentrated oil is far more concerning, because essential oils can affect the liver and nervous system in cats.
Don’t use concentrated oils on your cat, her bedding or her food, and keep scented sprays and oil burners out of rooms she uses. Dried flowers in bags and potpourri can be eaten too, so store them high up.
Lavender is sometimes suggested as a cat repellent spray for gardens. I don’t recommend it; there are safer options. If your cat has a pollen allergy or sensitive airways, strong scents and airborne pollen can also trigger sneezing.
Are hydrangeas poisonous to cats?
Yes, hydrangeas are poisonous to cats, causing vomiting, diarrhea and depression if leaves, buds or flowers are eaten. Serious poisoning is uncommon because cats rarely eat enough.
Hydrangeas contain compounds that can release small amounts of cyanide when chewed. In practice, a single nibbled petal is unlikely to cause more than a mild stomach upset, but a cat that eats lots of leaves or buds can become quite ill.
They’re popular in bridal bouquets, potted gift plants and front-yard shrubs. Indoors, keep potted hydrangeas where your cat can’t reach them. Outdoors, cats rarely chew established shrubs, but kittens might.
The ASPCA classes hydrangea as toxic; I’d describe it as moderately toxic. Call your vet if she eats a significant amount or seems weak or wobbly afterward.
Is baby’s breath toxic to cats?
Yes, baby’s breath is mildly toxic to cats, causing vomiting and diarrhea if eaten. It’s rarely serious, but it’s in so many bouquets that it’s worth knowing.
Baby’s breath is the small white flower that fills gaps in rose and carnation arrangements. Its tiny dry stems are fun to bat and chew, which is why it causes so many calls to poison lines despite low toxicity.
Signs are usually mild and pass within a day. Call your vet if your cat vomits repeatedly, has diarrhea for more than a day or stops eating.
When ordering flowers, ask for “no baby’s breath.” Florists can use waxflower or statice for the same airy effect, which PetMD lists among safe choices. Remove any sprigs from bouquets you receive before displaying them.
Are sunflowers safe for cats?
Yes, sunflowers are safe for cats: the ASPCA lists them as non-toxic to cats and dogs, so they’re one of the best flowers for a cat home. Eating a lot of petals or leaves can still cause mild stomach upset.
Sunflowers (Helianthus) make bright, cheerful bouquets and are easy to grow in gardens. Their size makes them less likely to be fully eaten, though cats do enjoy batting the petals.
Watch out for the heavy vase. A tall arrangement can be knocked over, spilling water and glass. Use a weighted vase, and keep fallen seeds and shells away; they’re not toxic but can be a choking hazard.
If your cat is bored, flowers are an easy target. Give her puzzle feeders and daily play so a bouquet isn’t the most interesting thing in the room.
Are daisies and mums toxic to cats?
Yes, common white daisies and chrysanthemums (mums) are toxic to cats, causing vomiting, diarrhea, drooling, wobbliness and skin irritation. Gerbera daisies are a different plant and are safe.
Mums are a popular fall plant on porches, and ox-eye daisies grow wild in yards. Both contain natural insecticides and irritant compounds that cats are sensitive to. Signs include hypersalivation, vomiting and diarrhea, and in larger amounts, a lack of coordination.
Most cases are mild to moderate and settle within a day with care. Keep potted mums off the floor and away from windowsills your cat uses.
If you love daisies, choose gerbera daisies or asters instead. Both look similar and are safe. The same caution applies to chamomile, a daisy relative; don’t give your cat chamomile tea or let her chew the plant.
Are peonies poisonous to cats?
Yes, peonies are mildly poisonous to cats, mainly causing vomiting, diarrhea and depression if eaten. The highest concentration of the toxin is in the woody parts of the plant.
Cut peony flowers in a vase are a low risk; most cats that chew a petal get mild stomach upset at worst. The ASPCA still lists peonies as toxic, so keep them out of reach.
Garden peonies are more of a concern if your cat chews stems or digs around roots. Older cats and kittens are more sensitive.
If your cat eats part of a peony, wipe her mouth, offer water and watch her for a day. If you’re unsure what she ate, snap a picture of the plant to show your vet; it saves time.
Are calla lilies and peace lilies dangerous for cats?
Calla lilies and peace lilies are toxic to cats, but they’re not true lilies and don’t cause kidney failure. They contain sharp oxalate crystals that irritate the mouth, causing pain, drooling, pawing at the face, vomiting and trouble eating.
The effect is immediate and usually limited to the mouth and throat, so most cats stop chewing quickly. Signs often improve within a few hours with water and a little milk or yogurt to coat the mouth, though your vet should advise you.
Rarely, swelling in the throat can make breathing hard. Seek help immediately if your cat struggles to breathe.
The key difference from true lilies: calla and peace lilies cause mouth pain, while Easter, tiger, Asiatic and daylilies cause kidney failure. If you can’t tell which “lily” your cat ate, treat it as an emergency until a vet confirms. Peace lilies are covered further in our upcoming houseplant guide.
Which cut flowers are safe for bouquets in a cat home?
The safest cut flowers for bouquets in a cat home are roses, sunflowers, gerbera daisies, snapdragons, freesia, alstroemeria, lisianthus, statice, asters, zinnias and orchids. Avoid lilies, tulips, daffodils, hydrangeas, carnations and baby’s breath.
| Instead of… | Choose… |
|---|---|
| Stargazer or Easter lilies | Alstroemeria, lisianthus or a moth orchid |
| Baby’s breath as a filler flower | Statice or waxflower |
| Carnations | Spray roses |
| Tulips and daffodils | Freesia and gerbera daisies |
| Hydrangeas | Snapdragons or zinnias |
Even a cat-safe bouquet can be a hazard. Rinse rose petals and stems to remove pesticides, toss the flower-food packet, and use a heavy vase. Remove ribbons and wires once you’ve unwrapped the arrangement.
Order with a note: “Cat household: no lilies, baby’s breath or carnations.” Most flower shops will happily build a pet-safe bouquet.
Which garden flowers are safe for cats?
Cat-safe garden flowers include roses, sunflowers, snapdragons, asters, pot marigolds, camellias and fuchsias. Avoid planting lilies, daylilies, oleander, azaleas, foxglove, lily of the valley and spring bulbs where cats roam.
Spring is when many bulbs pop up: tulips, daffodils, hyacinths and crocuses. If your cat goes outside or you bring cuttings in, plant bulbs in areas she can’t easily dig, or switch to safe annuals.
Shrubs need checking too. Mophead and lacecap hydrangea bushes are toxic, as are azaleas and oleander, which is common in warm states. Field daisies and peony bush roots are also mildly toxic.
Sunflowers are a fun cat-friendly addition, and birds love their seed heads, which gives indoor cats something to watch from the window. Avoid snail bait, fertilizer and weed killer in beds your cat visits.
What flowers are cats allergic to?
Cats can be allergic to any flower pollen, but true flower allergies are less common than poisoning. Strongly scented, high-pollen flowers like lilies, chrysanthemums, daisies and sunflowers are the most likely triggers.
Signs of an allergy include sneezing, itchy skin, over-grooming, ear scratching and, in cats with asthma, coughing or wheezing. Unlike poisoning, allergy signs appear whenever she’s exposed and fade when the flowers are gone.
Contact with sap can also cause skin irritation or dermatitis, especially from mums, daisies, carnations and tulips. You’ll see red, itchy skin on the chin, paws or belly.
If your cat has asthma or a known pollen sensitivity, choose low-pollen flowers like roses, orchids and snapdragons, and keep bouquets out of her sleeping area. A cat that coughs or breathes fast needs a vet.
What are the signs of flower poisoning in cats?
The most common signs of flower poisoning in cats are vomiting, drooling, diarrhea, not eating, hiding, lethargy and pawing at the mouth. Some flowers cause more serious signs that need urgent care.
| Sign | Possible flower or cause |
|---|---|
| Vomiting, hiding, not eating | Lilies (early kidney damage), tulips, daffodils |
| Drooling, pawing at mouth, trouble swallowing | Calla or peace lily, poinsettia, irritant sap |
| Abnormal heart rhythm, weakness, collapse | Oleander, lily of the valley, azalea, kalanchoe |
| Tremors, wobbliness, seizures | Azalea, sago palm, mums in large amounts |
| Bleeding, mouth sores | Puncture wounds from thorns, autumn crocus |
| Itchy skin, watery eyes, sneezing | Pollen or sap contact |
Woody parts such as bark and roots, and bulbs, tend to be more toxic than flowers. Signs can start within minutes or be delayed by a day, so don’t assume she’s fine because she looks normal now.
What should you do if your cat eats a flower?
If your cat eats a flower, remove the plant, check her mouth, identify exactly what she ate and call your vet or a poison line right away. For lilies, go straight to the vet.
- Move her away from the plant and pick up any fallen leaves or pollen.
- Identify the plant: look for the plant tag, the Latin name or ask your florist. Common nicknames can be misleading.
- Call for advice: your vet, ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661. A consultation fee applies.
- Don’t give home remedies or try to cause vomiting unless a vet tells you to.
- Wipe pollen off her fur with a damp cloth so she can’t lick it.
For lily exposure, treatment started within 6 hours, with decontamination and IV fluids, gives the best chance of protecting her kidneys. For non-urgent questions, Dutch offers online vet consults.

How do you keep cats away from flowers?
Keep cats away from flowers by placing them out of reach or in rooms she can’t enter, choosing only cat-safe varieties, and giving her a safe alternative to chew. Deterrents help but aren’t foolproof.
- Height: use hanging baskets, wall shelves and closed rooms for any plant you’re unsure of.
- Alternatives: grow cat grass so she has something to chew instead of your houseplant.
- Texture: cover soil with large pebbles or pine cones so she won’t dig, and use a bark mix she can’t scatter.
- Weight: heavy vases and pots that won’t tip, with no tall stems hanging over the edge.
- Garden: fence or net garden beds and avoid toxic shrubs where outdoor cats roam.
Cats chew plants out of boredom, curiosity or a wish for fiber. Daily play and enrichment reduce the urge. Meow Greens is a greens supplement some owners use for cats that crave plants; ask your vet if it suits yours.

Frequently asked questions
Is eucalyptus safe for cats?
No, eucalyptus is toxic to cats; the leaves and especially the concentrated oil can cause drooling, vomiting, diarrhea, weakness and depression. Don’t use eucalyptus or lemon oils in a diffuser around cats, and keep eucalyptus stems out of bouquets and shower bundles. Lavender oil carries similar risks.
Is chamomile safe for cats?
No, the ASPCA lists chamomile as toxic to cats, causing skin irritation, vomiting and diarrhea, and with long-term use, a bleeding tendency. It contains volatile oils and sesquiterpene lactones. Don’t give your cat chamomile drinks or remedies. Unlike sunflower seeds, it’s not a safe snack. If she ate a lot, call your vet rather than trying to make her vomit at home.
Are marigolds poisonous to cats?
Pot marigolds are low risk for cats, but French and African marigolds can irritate the mouth, skin and stomach. Their sap may cause mild drooling or a contact allergy, and they don’t contain the pyrethrins found in mums. Most cases are mild.
Is vase water or flower food dangerous for cats?
Yes, vase water can be dangerous, especially if lilies were in the vase, because lily pollen and toxins dissolve into the water. Cut-flower food packets can also upset the stomach. Change water daily, use a covered vase, and keep dried flower sachets away from cats. Around Valentine’s Day and Mother’s Day, call the ASPCA hotline if she drank from a lily vase.
