My cat ate Chestnut Dioon — what to do

Step by step

  1. Take chestnut dioon away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My cat ate chestnut dioon — FAQ

Is chestnut dioon poisonous to cats?

Yes — the ASPCA lists Chestnut Dioon (Dioon edule) as toxic to cats. Dioon edule contains cycasin (methylazoxymethanol glucoside), the same hepatotoxic glycoside found in all Zamiaceae cycads including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. Ingestion causes vomiting, bloody diarrhoea, liver necrosis, and can be fatal. Seeds are particularly high in toxin concentration. Emergency veterinary treatment is required for any suspected ingestion.

How serious is it if my cat ate chestnut dioon?

Chestnut Dioon is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Dioon edule contains cycasin (methylazoxymethanol glucoside), the same hepatotoxic glycoside found in all Zamiaceae cycads including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. Ingestion causes vomiting, bloody diarrhoea, liver necrosis, and can be fatal. Seeds are particularly high in toxin concentration. Emergency veterinary treatment is required for any suspected ingestion. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep chestnut dioon well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
