Peppermint
Mentha × piperita
Peppermint (Mentha x piperita) is mildly toxic to cats. The plant is rich in menthol and pulegone — monoterpenoid compounds that cats cannot efficiently metabolise due to limited hepatic glucuronidase activity. While fresh plant nibbling usually causes only mild GI upset, peppermint essential oil is significantly more concentrated and far more dangerous.
重要提醒
Toxic compounds: menthol, pulegone, and related monoterpenoids; essential oil is 50-100x more concentrated than fresh leaves
Mechanism: impaired feline hepatic metabolism of terpenoids leads to GI irritation and liver stress; high doses cause CNS depression
Symptoms: vomiting, diarrhea, drooling, lethargy; peppermint oil can cause tremors, weakness, and liver damage
Never apply peppermint oil to a cat's skin or fur — topical exposure causes rapid systemic absorption
Diffusing peppermint oil in closed spaces is also harmful; use in well-ventilated areas away from cats
