My cat ate Common Poppy — what to do
Step by step
- Take common poppy 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 the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and 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.
My cat ate common poppy — FAQ
Is common poppy poisonous to cats?
Yes — the ASPCA lists Common Poppy (Papaver rhoeas) as toxic to cats. Papaver rhoeas is listed as toxic to dogs, cats, and horses. It contains isoquinoline alkaloids including rhoeadine, coptisine, and allotropine, which act as CNS depressants and produce opioid-like toxicity. Ingestion can cause sedation, ataxia, pinpoint pupils (dogs) or dilated pupils (cats), drooling, vomiting, respiratory depression, and in severe cases coma. All parts of the plant — including the green stems, leaves, sap, and unripe seed heads — are considered toxic; the milky sap is the most potent. Contact the ASPCA Animal Poison Control Center (888-426-4435) if ingestion is suspected.
How serious is it if my cat ate common poppy?
Common Poppy 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.
