My cat chewed a daffodil bulb, not a green onion — which is more toxic for a 4 kg senior cat?

Short answer

Daffodil bulbs are much more toxic. They contain lycorine, which causes drooling, vomiting, and abdominal pain, especially dangerous for a small, senior cat. Green onions are also toxic to cats but typically require a larger amount to cause severe issues. Call your vet or the ASPCA Poison Control (888-426-4435) right away, tell them it was a daffodil bulb, and rinse your cat's mouth gently with water.

Why is this dangerous?

Tulips and hyacinths contain tulipalin A and B, and daffodils contain lycorine and other alkaloids. The concentration is highest in the bulb, lower in the stem and leaves.

Dogs are poisoned most often in spring when they dig up newly planted bulbs, or in winter when bulbs are forced indoors in pots.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Drooling, lip smacking, pawing at the mouth
  • Vomiting, sometimes repeated, and diarrhoea
  • Abdominal pain, not eating, lethargy
  • Wobbliness or tremors after eating several bulbs
  • Heart rhythm changes, low blood pressure and collapse in large ingestions

What to do right now

  1. Call your vet or a poison line and say how many bulbs and which flower.
  2. Rinse the mouth with water and wipe any plant sap off the fur and paws.
  3. Do not induce vomiting yourself — ask the vet first, especially if the pet is already vomiting.
  4. Dig up and fence off bulbs; keep forced pots on a shelf a pet cannot reach.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
