Daffodil

What it does to a cat.

Yes — daffodils are toxic to cats. The ASPCA lists Narcissus spp. — including jonquils and paper whites — as toxic to cats, dogs, and horses. The toxic principle is lycorine and related alkaloids, which act as potent GI irritants and, at higher doses, affect the cardiovascular and nervous systems. The bulb is the most poisonous part.

Symptoms usually begin within 15 minutes to two hours: drooling, vomiting (sometimes with bulb fragments), abdominal pain, and diarrhea. Larger ingestions — typically when a cat chews a bulb rather than nibbles a leaf — can progress to tremors, convulsions, low blood pressure, and cardiac arrhythmia.

Where cats meet daffodils

Outdoor cats encounter daffodils in spring borders and naturalised lawns. Indoor cats meet them in two specific high-risk forms: cut-flower bouquets and forced-bulb kits. The forced-bulb kits — paper whites and miniature Narcissus sold as winter gift items — are particularly dangerous because the bulb sits exposed in a shallow bowl, often at counter or table height.

The bulb problem

Of all the parts of a daffodil, the bulb carries the highest alkaloid load. A cat that chews an exposed forced bulb or digs one up from a planter receives a much larger dose than one nibbling a leaf or petal. Bulb ingestions are the cases that produce tremors, seizures, and cardiac signs — and the ones that need ER-level treatment.

Vase water counts

The water in a vase of cut daffodils carries enough alkaloid to make a cat sick on its own. If a cat drinks from flower water, treat it as an ingestion: call your vet or ASPCA Poison Control at (888) 426-4435 and watch for GI signs.

Safer spring flowers

For trumpet-shaped or cheerful spring blooms without the alkaloid risk, orchids and African violets are ASPCA non-toxic and bring the same seasonal colour indoors. For cut flowers, roses are the obvious replacement. See our pages on tulips — another Amaryllidaceae-adjacent spring bulb you should not have around cats — and lilies, the deadliest spring flower of all.

If exposure has happened

Call your vet or ASPCA Animal Poison Control at (888) 426-4435 immediately. Bring a piece of the plant or a photo — especially if a bulb was involved. Treatment is supportive: IV fluids, anti-emetics, and cardiac monitoring for severe cases. Most cats recover fully with prompt care; the danger is in delay.
