Are Daffodils toxic to cats?
Yes. Daffodils contain lycorine and other alkaloids, especially in the bulb. Cats eating daffodil bulbs or flowers can become seriously unwell.

Key facts
- Verdict: No — dangerous to cats. Daffodils should never be given deliberately.
- Category: Toxic garden plant
- Onset: Signs can start 0–4 hours — see the full timeline below.
- If it's already happened: Call your vet now, or the Animal PoisonLine on 01202 509000 (24/7, charges apply) — see the emergency steps below.
If your cat has just eaten daffodils
- Move your cat away from any remaining daffodil. Do not try to make them vomit at home — this is dangerous in cats and rarely works.
- Note how much was eaten and when, and keep the packaging or a photo of the plant/substance if you can.
- Call your vet immediately, even out of hours. Tell them your cat's weight, what they ate, and when.
- If you can't reach your vet, call Animal PoisonLine (01202 509000) — paid triage, 24/7 for guidance. They can advise on urgency and route you to emergency care.
What's the full picture?
Daffodil bulbs contain the highest concentration of toxic alkaloids, but the flowers, leaves, stems, and even the water in a daffodil vase are also dangerous.
Spring is peak daffodil emergency season. Cats drinking vase water or chewing stems left on a coffee table are common exposures.
Daffodils are poisonous to cats — every part of the plant, from flower to bulb. The main culprit is lycorine, an alkaloid concentrated most heavily in the bulb, alongside microscopic calcium oxalate crystals in the sap that irritate the mouth and throat. In a UK spring, exposure is hard to avoid: daffodils are in gardens, verges, and cut-flower bunches from February to May, and the danger doesn't end with the plant itself — the vase water daffodil stems stand in becomes toxic too.
Most feline cases are mild to moderate: drooling, vomiting, and diarrhoea within a few hours of chewing a flower or stem, settling within 24 hours with supportive care. Bulb ingestion is more serious — larger doses of lycorine can cause abdominal pain, tremors, low blood pressure, and heart rhythm disturbances. Cats that dig up or chew stored bulbs (or drink daffodil vase water) should see a vet rather than be watched at home.
Prevention is straightforward: keep cut daffodils in rooms your cat doesn't use, empty and rinse vases promptly, and store spring bulbs somewhere sealed. If your cat has chewed any part of a daffodil, ring your vet or the Animal PoisonLine on 01202 509000 — bring a note of how much was eaten and when.

Questions owners ask
My cat chewed a daffodil leaf. Is a leaf less dangerous than the bulb?
The bulb is the most toxic part, but leaves still contain significant lycorine and other alkaloids. Any daffodil ingestion needs veterinary assessment — severe vomiting and GI signs can start within an hour.
The flower water in my vase has daffodils in it. Is that dangerous if my cat drinks from it?
Yes. Daffodil stem sap leaches into vase water and the water itself becomes mildly toxic. Cats sometimes prefer vase water over their own water bowl. Keep daffodil arrangements out of cat-accessible areas.
When is daffodil poisoning most common in the UK?
Peak daffodil emergencies happen in February to April as daffodils bloom in UK gardens, and January-February for forced indoor bulbs bought for early spring. Narcissus (including paperwhites) share the same toxins.
Are daffodils poisonous to cats?
Yes — all parts of the daffodil are poisonous to cats, with the bulb the most dangerous part. Chewing flowers or stems typically causes drooling, vomiting, and diarrhoea; eating bulb material can cause tremors and heart rhythm problems and needs a vet.
Is daffodil vase water dangerous to cats?
Yes. Lycorine and other alkaloids leach from cut daffodil stems into the vase water, so a cat drinking from the vase can be poisoned without touching the plant. Keep vases out of reach and empty them promptly.
If your cat keeps returning to the wrong plant, a pet-safe plant deterrent spray can break the habit without harm.

About this guidance
Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.
This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.
