Cinnamon

Caution Herbs

Cinnamon is not acutely lethal to cats in the tiny amounts found in household foods, but it is not a safe or appropriate addition to a cat's diet. The spice contains cinnamaldehyde and coumarin compounds that can irritate mucous membranes, trigger allergic skin reactions, and cause liver stress with repeated or concentrated exposure. Owners should keep cinnamon sticks, powders, and especially cinnamon essential oil well away from their cats.

Clinical note: Irritant herb — cinnamaldehyde causes oral/skin sensitisation; coumarin poses hepatotoxic risk in cats
