Is Cyclamen toxic to cats?
Yes. Cyclamen — especially the tubers — contain saponins that cause vomiting, diarrhoea, and in severe cases heart rhythm problems.

Key facts
- Verdict: No — dangerous to cats. Cyclamen should never be given deliberately.
- Category: Toxic garden plant
- Onset: Signs can start 0–6 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 cyclamen
- Move your cat away from any remaining cyclamen. 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?
Cyclamen are popular houseplants and winter bedding plants. The underground tuber is the most toxic part, but the leaves and flowers also contain the toxic compounds.
Small nibbles usually cause GI upset; larger ingestions (especially of tubers) can be more serious.

Questions owners ask
Is the whole cyclamen plant equally risky, or just the tuber?
The underground tuber is the most concentrated source of the toxic saponins and is the highest-risk part, which matters most for outdoor cats that might dig up bedding cyclamen or access stored tubers before planting. The leaves and flowers also contain the toxic compounds, so a houseplant cyclamen nibbled by an indoor cat still needs the same vigilance, just with a somewhat lower likelihood of severe symptoms than a tuber ingestion.
When would cyclamen poisoning need emergency treatment rather than home monitoring?
Small nibbles that cause only vomiting and diarrhoea in the first 6 hours can often be monitored with your vet's guidance, but any heart rhythm changes or seizures — which can appear at the 6–24 hour mark, especially after tuber ingestion — need immediate emergency treatment. Call your vet as soon as you know or suspect cyclamen ingestion so they can advise based on what part of the plant and how much was involved.
Are there safe flowering houseplant alternatives to cyclamen?
African violets and orchids are both generally considered cat-safe flowering houseplants that can offer similar colour and interest indoors without the saponin-related toxicity risk of cyclamen. As always, verify any specific plant variety against a current toxic-plant reference before bringing it home.
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.
