Lavender
Lavandula spp.
Lavender (Lavandula spp.) is mildly toxic to cats due to the essential oils concentrated in its flowers and foliage — primarily linalool and linalyl acetate. Cats lack the liver enzyme glucuronyl transferase needed to metabolise these terpenoid compounds effectively, so even small exposures from chewing flowers or inhaling concentrated diffuser oil can cause upset.
重要提醒
Toxic compounds: linalool and linalyl acetate (monoterpenoid compounds); concentrated in flowers and essential oil
Mechanism: cats cannot adequately glucuronidate terpenoids, allowing accumulation that irritates the GI tract and mildly stresses the liver
Symptoms: vomiting, diarrhea, drooling, lethargy; essential oil diffusers can cause respiratory irritation and systemic exposure via inhalation
A few leaves are unlikely to cause serious harm; essential oil products are far more concentrated and should be kept away from cats
Contact your vet if your cat ingests lavender oil or essential oil products
