My cat ate Pyramidalis Arborvitae — what to do
Step by step
- Take pyramidalis arborvitae 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 pyramidalis arborvitae — FAQ
Is pyramidalis arborvitae poisonous to cats?
Yes — the ASPCA lists Pyramidalis Arborvitae (Thuja occidentalis 'Pyramidalis') as mildly toxic to cats. Thuja occidentalis is not individually listed on the ASPCA toxic or non-toxic plant lists; treat with caution and verify with a vet. Foliage and oil contain thujone, which in quantity can cause drooling, vomiting, diarrhoea, and in severe cases neurological signs in dogs and cats. Reported poisonings are uncommon, but prevent ingestion and monitor pets.
How serious is it if my cat ate pyramidalis arborvitae?
Pyramidalis Arborvitae is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.
What symptoms should I watch for?
Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Thuja occidentalis is not individually listed on the ASPCA toxic or non-toxic plant lists; treat with caution and verify with a vet. Foliage and oil contain thujone, which in quantity can cause drooling, vomiting, diarrhoea, and in severe cases neurological signs in dogs and cats. Reported poisonings are uncommon, but prevent ingestion and monitor pets. 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?
