Are Poinsettias toxic to cats?

Caution

Caution. Poinsettias have a worse reputation than they deserve — the toxicity is mild, causing mouth irritation and stomach upset. Not the deadly Christmas plant of urban legend.

If your cat has eaten poinsettias

  1. Wipe any sap from your cat's mouth with a damp cloth.
  2. Monitor for vomiting and diarrhoea over 24 hours.
  3. Call your vet if symptoms are persistent or severe.

What's the full picture?

Poinsettias contain an irritant latex sap that causes mouth irritation, drooling, and mild GI upset. The 'deadly Christmas plant' reputation is a persistent myth — serious poisoning from poinsettia is very rare.

Still worth keeping out of reach, and worth a vet call if ingestion causes repeated vomiting or throat swelling, but the panic response isn't warranted.

Symptoms to watch for

Immediately
Drooling, pawing at mouth.
0–12 hours
Mild vomiting, loss of appetite.

Questions owners ask

Are poinsettias really deadly?

No — this is a long-standing myth. They can cause unpleasant symptoms but are rarely dangerous. The real Christmas plant emergencies are lilies, holly berries (in large amounts), and mistletoe.

If you're worried right now

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.

Entries are reviewed and updated as new research emerges. Spotted an error? Let us know — corrections are investigated and applied within 24 hours. For more context on how we work, see about and our full disclaimer.
