What to do after ingestion
Drooling, vomiting, abdominal pain, loose stools or diarrhoea, poor appetite, lethargy and hiding; oil exposure can bring mouth burning, repeated swallowing and, in severe cases, trouble breathing.
**Contact a vet immediately** after cinnamon oil or a large amount of powder, or for persistent vomiting, pain, drooling or breathing difficulty, and never induce vomiting at home or feed home remedies.
Cats are especially sensitive to essential oils, so **cinnamon oil must be avoided completely**: its cinnamaldehyde irritates the mouth and gut, causing drooling, vomiting and pain; **a lot of powder irritates the gut too**; a cat has no need for this spice.
What to do after ingestion
Drooling, mouth and tongue irritation, vomiting, abdominal pain, loose stools or diarrhoea and poor appetite; inhaled powder can bring coughing, sneezing and trouble breathing, and oil makes signs worse.
A pinch used as seasoning means stopping and watching; **contact a vet immediately** after cinnamon oil, a cinnamaldehyde supplement or a lot of powder, or for persistent vomiting, pain, coughing or breathing trouble, and never induce vomiting at home.
Cinnamon is not highly poisonous, but **a large amount irritates the mouth and gut**, and its cinnamaldehyde causes burning, vomiting and pain; **dry powder is easily inhaled**; **cinnamon oil and cinnamaldehyde supplements are far riskier concentrates**.
