Why cinnamon harms pets
Cinnamon contains coumarin and essential oils that irritate the gastrointestinal lining and can depress the central nervous system.
In large amounts the compounds can cause hypoglycemia and liver inflammation.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of cinnamon poisoning
- Repeated vomiting within 1‑3 hours of ingestion
- Diarrhoea that may be watery and frequent
- Lethargy and wobbling by the evening
- Trembling or seizures due to low blood sugar
- Yellowish eyes indicating liver stress
What to do right now
- Call your vet or a poison control line immediately
- Gather the packaging or note the amount of cinnamon ingested
- Do not induce vomiting if the cinnamon was in oil form because of aspiration risk
- Offer small amounts of water to prevent dehydration
- Monitor blood sugar and be ready for IV glucose at the clinic
