My cat ate Swamp White Oak — what to do
Step by step
- Take swamp white oak 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 swamp white oak — FAQ
Is swamp white oak poisonous to cats?
Yes — the ASPCA lists Swamp White Oak (Quercus bicolor) as toxic to cats. Oak (Quercus) is listed by the ASPCA as toxic to dogs, cats and horses. Tannins (gallotannic and tannic acid) are the toxic principle, concentrated in acorns, buds and young leaves. Ingestion typically causes vomiting, diarrhoea (possibly bloody), lethargy, abdominal pain and inappetence; significant or repeated intake can damage the kidneys and liver, and whole acorns may cause obstruction. Keep acorns and fallen leaves away from pets and livestock.
