Yes, daffodils are poisonous to cats, and any contact or nibbling should be treated seriously. If you think your cat has chewed a daffodil or its bulb, contact a vet or emergency clinic immediately.

What makes daffodils toxic?

Daffodils (Narcissus spp.) contain toxic alkaloids, mainly lycorine , found in every part of the plant. The bulbs have the highest concentration and are considered the most dangerous if a cat digs them up or chews them.

Common effects of these toxins include:

  • Gastrointestinal irritation (especially from lycorine).
  • Potential effects on the nervous and cardiovascular systems in more serious cases.

Symptoms of daffodil poisoning in cats

Signs can appear within a few hours of ingestion and may vary from mild to severe.

Watch for:

  • Vomiting, drooling, lack of appetite, abdominal pain, diarrhea.
  • Lethargy, tremors, unsteadiness, low blood pressure, slow heart rate, or collapse in severe cases.
  • Skin irritation (“daffodil picker’s rash”) if sap contacts sensitive skin, though this is less common in cats.

What to do if your cat ate a daffodil

Do not wait to see if your cat “gets better” on their own; prompt care greatly improves outcomes.

Steps:

  1. Remove access to the plant (cat away from the flowers, and flowers out of reach).
  1. Call your vet or an emergency veterinary clinic, describing how much and which part of the plant was eaten.
  1. Do not induce vomiting or give home remedies unless a vet specifically instructs you to do so.

Vets may provide treatments such as anti-vomiting medication, fluids, and monitoring of heart and blood pressure, depending on severity.

Keeping cats safe around daffodils

Because daffodils are common in bouquets, gardens, and spring decorations, prevention is key.

Safer habits:

  • Avoid planting daffodils where curious outdoor cats dig, or fence off beds if possible.
  • Keep cut daffodil arrangements out of reach or choose non-toxic flowers for indoor displays.
  • Learn which other common plants (like lilies and tulips) are also toxic to cats and avoid them in cat-accessible areas.

TL;DR: Daffodils are poisonous to cats; the whole plant, especially the bulb, can cause vomiting, stomach upset, and in serious cases neurological and heart issues, so keep them out of reach and call a vet immediately if your cat may have eaten any part.
