今すぐやるべきこと
- 1
Step 1: Wash Your Cat If Oil Is On Fur/Skin
Use Dawn dish soap (cuts oil) to wash off any topical exposure. Rinse thoroughly. Do NOT use water alone — oil repels water.
- 2
Step 2: Remove From Exposure Source
Turn off diffusers, remove oil containers, and ventilate the area. Move your cat to fresh air.

Step 3: Call Poison Control
📞 <strong>ASPCA Poison Control:</strong> (888) 426-4435. Bring the oil bottle — tell them the botanical name and phenol/terpene content if listed.

Step 4: Do NOT Induce Vomiting
⚠️ Essential oils have high aspiration pneumonia risk. Vomiting can cause oil to enter lungs. Go to vet for safe decontamination.
その背後の科学
猫は、テルペン（d-リモネン、アルファ-テルピネオール）とフェノール（オイゲノール、チモール）の第II相グルクロン酸抱合に必要なUDP-グルクロノシルトランスフェラーゼ（UGT1A6およびUGT1A9）酵素を欠いています。これらの化合物は肝膽道系に蓄積し、肝毒性および神経毒性を引き起こします。また、猫は血液脳関門でのP-糖タンパク質排出輸送体も欠如しており、CNSへの曝露が増加します。ティーツリー油（Melaleuca alternifolia）のモノテルペンは用量依存性にCNS抑うつ、失調症、低体温を引き起こします。皮膚に10mLでも、猫にとって致命的となる可能性があります（ASPCA、2023）。
よくある質問
Why are essential oils toxic to cats?
Cats lack UDP-glucuronosyltransferase (UGT) enzymes needed to metabolize certain compounds in essential oils (terpenes, phenols, ketones). This makes them 10x more sensitive than dogs to tea tree oil, citrus oils, eucalyptus, peppermint, and pine oils. Even topical application on skin can cause toxicity if the cat licks it off.
Which essential oils are most dangerous for cats?
Most dangerous: Tea tree (melaleuca), wintergreen, peppermint, pine, eucalyptus, citrus (limonene, linalool), cinnamon, clove, ylang ylang, birch, and thyme. Tea tree oil is most commonly reported — even 10-20mL on skin can be fatal. Diffusers are also dangerous as cats inhale droplets and groom them from fur.
What are the symptoms of essential oil poisoning in cats?
Symptoms depend on oil type and route: (1) Ingestion: drooling, vomiting, tremors, ataxia, weakness, hypothermia. (2) Skin absorption: lethargy, hypersalivation, liver damage. (3) Inhalation: respiratory distress, aspiration pneumonia. Tea tree oil specifically causes severe hypothermia and ataxia within 2-8 hours.
Are essential oil diffusers dangerous for cats?
Yes, diffusers pose three risks: (1) Inhaled droplets settle on fur and are groomed off, causing ingestion. (2) Volatilized oils irritate feline respiratory passages (cats have efficient smell but sensitive airways). (3) Concentrated oil in the diffuser water can be spilled and licked. Use diffusers only in well-ventilated rooms your cat cannot access.
