My cat ate Giant Dioon — what to do
Step by step
- Take giant dioon away and remove any plant material from your cat's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- Call your vet, or a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. Follow their advice.
- 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
My cat ate giant dioon — FAQ
Is giant dioon poisonous to cats?
Yes — the ASPCA lists Giant Dioon (Dioon spinulosum) as toxic to cats. Dioon spinulosum contains cycasin (methylazoxymethanol glucoside), the potent hepatotoxic compound present throughout the Zamiaceae family including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. All parts — seeds, leaves, and roots — are toxic; seeds contain the highest concentrations. Ingestion causes vomiting, bloody diarrhoea, liver failure, and is potentially fatal. Seek immediate emergency veterinary care if ingestion is suspected.
How serious is it if my cat ate giant dioon?
Giant Dioon is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, 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 spinulosum contains cycasin (methylazoxymethanol glucoside), the potent hepatotoxic compound present throughout the Zamiaceae family including Cycas revoluta (sago palm), which the ASPCA lists as toxic to cats and dogs. All parts — seeds, leaves, and roots — are toxic; seeds contain the highest concentrations. Ingestion causes vomiting, bloody diarrhoea, liver failure, and is potentially fatal. Seek immediate emergency veterinary care if ingestion is suspected. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
