花葉萬年青

貓咪可能出現的症狀

由嚴重到輕微排列。

1. 1
   嘴巴、舌頭、嘴唇和喉嚨劇烈灼熱、刺激與發炎 咀嚼或咬到植物後立即發生。 · The plant contains needle-like crystals (raphides) that are forcefully ejected into the soft tissues when the plant is chewed. This immediate, intense pain often limits the amount a cat will ingest because they stop chewing right away.Excessive Drooling (Hypersalivation)
2. 2
   呼吸困難以及舌頭／喉嚨腫脹（水腫） 發炎開始後快速出現。 · While death is infrequent, severe inflammation and swelling of the tongue and pharynx (glottal edema) can obstruct the airway, making it difficult for the cat to breathe. This requires urgent veterinary care.
3. 3
   過度流口水或唾液分泌過多 攝入後立即至數分鐘內。 · The cat may also exhibit head shaking or paw at their mouth in an attempt to remove the irritant.
4. 4
   嘔吐、吞嚥困難與食慾不振 立即（吞嚥困難）至短期（嘔吐）。 · The cat may be unable or unwilling to eat (anorexia) due to the oral pain and swelling. Diarrhea is possible but less common than the oral symptoms.

重要提醒

花葉萬年青是受歡迎的熱帶室內植物。它對貓有毒，因為葉片和莖中的特殊細胞含有不溶性草酸鈣結晶（針晶，raphides）。當貓咬或咀嚼植物時，這些針狀結晶會被強力釋放到口腔黏膜，立即造成劇烈疼痛與發炎。

• 毒性化合物：不溶性草酸鈣結晶（針晶）以及會加劇反應的蛋白分解酶。
• 機制：機械性刺入口腔與喉嚨黏膜，造成劇烈灼熱與腫脹。
• 症狀：突然的口腔疼痛、劇烈流口水、用爪子抓嘴、吞嚥困難、舌頭與嘴唇腫脹、嘔吐。
• 嚴重情況：喉嚨腫脹可能影響呼吸，請立即尋求獸醫照護。
