Tea Tree
Melaleuca alternifolia
Tea Tree (Melaleuca alternifolia) essential oil is highly toxic to cats. Unlike many herbal products, tea tree oil causes severe toxicity even in very small topical doses — a few drops applied to the skin can cause life-threatening reactions. Cats absorb the oil rapidly through skin, and their livers cannot metabolise the terpene compounds.
重要提醒
Toxic compounds: terpene-4-ol, alpha-terpinene, and related monoterpenoids; concentrated in essential oil (never use on or near cats)
Mechanism: cats lack sufficient glucuronyl transferase to metabolise these terpenoids, causing rapid toxic accumulation affecting the CNS and liver
Symptoms: drooling, vomiting, ataxia, weakness, tremors, low body temperature, collapse; onset within hours of topical application
Topical application is the most common cause of toxicity — never use tea tree oil as a flea treatment or skin remedy for cats
Any tea tree oil exposure is a veterinary emergency — rinse off immediately and contact a vet
