茶樹

貓咪可能出現的症狀

由嚴重到輕微排列。

1. 1
   肝損傷，可能進展為肝衰竭 Not explicitly specified in the sources. · Because cats lack the specific enzymes to metabolize essential oils, the toxins accumulate and cause serious organ damage. Extreme cases of toxicity can cause complete liver failure and death.
2. 2
   發抖、震顫、步態不穩（共濟失調）、倒地以及癲癇發作 Not explicitly specified in the sources. · Essential oils heavily impact the central nervous system. If the toxicity progresses to collapse or seizures, it is a life-threatening emergency.
3. 3
   沮喪、嗜睡或精神沉鬱 Not explicitly specified in the sources. · This is a primary, highlighted symptom specifically associated with tea tree oil poisoning in cats.
4. 4
   低體溫（異常低的體溫） Not explicitly specified in the sources. · Alongside depression, hypothermia is explicitly noted as a direct consequence of tea tree oil exposure in felines.
5. 5
   皮膚疼痛、發紅或化學灼傷 Not explicitly specified in the sources. · Direct skin contact with undiluted essential oils causes localized damage. However, the sources warn that even if there is no visible damage to the skin, you should not assume the cat is safe from systemic poisoning.
6. 6
   呼吸困難或張口呼吸 Not explicitly specified in the sources. · While toxic effects from simply inhaling oils from standard reed diffusers or plugins are rare due to dilution, the risk of severe respiratory distress increases if you use nebulized or ultrasonically diffused neat (undiluted) essential oils, or if the cat has pre-existing medical conditions like asthma.
7. 7
   劇烈流口水與嘔吐 Not explicitly specified in the sources. · These are common signs of general essential oil poisoning, often occurring if a cat ingests the liquid directly or licks it off its fur during grooming.

重要提醒

茶樹精油（來自 Melaleuca alternifolia）對貓有劇毒，絕對不應在牠們身上或周遭環境中使用。貓咪會經由皮膚吸收、吸入精油蒸氣，或舔毛時食入這些有毒化合物，並可能在短時間內引發嚴重中毒。 茶樹精油含有萜烯類化合物，貓的肝臟無法有效分解這些成分，導致毒素在體內迅速累積，影響中樞神經系統和肝臟功能。即使只是幾滴的量，也可能引發威脅生命的反應。 茶樹精油中毒的症狀包括走路不穩或失去協調能力、虛弱、顫抖、體溫過低和嘔吐。如果你懷疑貓咪接觸到茶樹精油，這屬於緊急醫療情況。請立即用洗碗精和清水替貓咪清洗，並馬上聯絡獸醫或急診動物醫院。

• 有毒化合物：4-松油醇 (terpene-4-ol)、α-萜品烯 (alpha-terpinene) 及其相關單萜類化合物；高度濃縮於精油中（絕不可在貓咪身上或附近使用）
• 機制：貓咪缺乏足夠的葡萄糖醛酸轉移酶來代謝這些萜類，導致毒性迅速蓄積並影響中樞神經系統和肝臟
• 症狀：流口水、嘔吐、共濟失調、虛弱、震顫、體溫低、倒地；通常在局部塗抹後數小時內發作
• 局部塗抹是中毒最常見的原因——絕不可將茶樹油作為貓咪的除蚤藥或皮膚藥物
• 任何茶樹油接觸皆屬獸醫急診——請立即洗淨並聯繫獸醫師
