My cat ate Common Wormwood — what to do
Step by step
- Take common wormwood 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 wormwood — FAQ
Is common wormwood poisonous to cats?
Yes — the ASPCA lists Common Wormwood (Artemisia absinthium) as toxic to cats. Artemisia absinthium contains the monoterpene thujone and the bitter glycoside absinthin. The North Carolina Extension Plant Toolbox lists it as a problem for both cats and dogs, and veterinary toxicology sources note that ingestion of significant quantities can cause vomiting, diarrhoea, neurological signs including tremors or seizures, and liver damage. Thujone acts as a GABA-A receptor antagonist. Keep pets away from this plant.
How serious is it if my cat ate common wormwood?
Common Wormwood 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. Artemisia absinthium contains the monoterpene thujone and the bitter glycoside absinthin. The North Carolina Extension Plant Toolbox lists it as a problem for both cats and dogs, and veterinary toxicology sources note that ingestion of significant quantities can cause vomiting, diarrhoea, neurological signs including tremors or seizures, and liver damage. Thujone acts as a GABA-A receptor antagonist. Keep pets away from this plant. 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?
