Clove
Syzygium aromaticum
Clove (Syzygium aromaticum) is a common kitchen spice, but it is not safe for cats, especially in the form of clove essential oil. The main concern is eugenol, a highly concentrated and strongly irritating plant compound found in cloves. Humans can usually break down these compounds more effectively, but cats have a much more limited ability to process them in the liver. Because of this, eugenol and related phenolic compounds may build up in a cat’s body and cause poisoning. In serious cases, they may even damage the liver. Clove essential oil is more dangerous than dried cloves because it is highly concentrated and can be absorbed through the skin, mouth, or mucous membranes. Even a small amount of exposure may cause irritation or toxicity. If you have cats at home, avoid using clove essential oil and keep cats away from clove products so they cannot lick, chew, or have prolonged contact with them.
Important Notes
Symptoms: Drooling, vomiting, lethargy, loss of coordination (ataxia), and muscle tremors from exposure; liver damage signs (jaundice, loss of appetite) with larger exposures; respiratory distress if inhaled.
Essential oil is far more dangerous than whole cloves: Concentrated clove oil can cause serious poisoning with just a few drops. Whole cloves or ground clove in small amounts pose lower but still real risk.
Action: Seek veterinary care immediately if a cat has been exposed to clove essential oil — on the skin, ingested, or via diffuser. Liver damage can progress rapidly.
