看到家里的貓咪突然吐出黃色液體，許多主人都會心頭一緊。這種黃水可能是胃液混合膽汁的表現，看似普通，但背后可能隱藏著致命風險。有些貓咪在吐黃水后迅速虛弱甚至死亡，這讓鏟屎官們既心疼又困惑。為什么看似簡單的嘔吐會引發如此嚴重的后果？其實，貓咪吐黃水往往是身體發出的“求救信號”，涉及消化系統疾病、傳染性病毒甚至器官衰竭等問題。只有了解背后的原因，才能及時采取正確的措施，為貓咪爭取生機。

一、消化系統疾病：從毛球癥到致命危機

貓咪舔毛是天性，但吞入的毛發若長期堆積成團，就會形成毛球癥。當毛球刺激胃壁時，貓咪會頻繁干嘔、吐黃水，甚至因腸道堵塞引發壞死。此時若不及時喂食化毛膏或送醫，可能導致貓咪脫水或感染性休克。

另一種常見問題是急性腸胃炎。誤食變質食物、異物或過敏原會引發胃黏膜損傷，貓咪不僅吐黃水，還可能伴隨腹瀉、發燒。若拖延治療，腸道功能紊亂會加劇電解質失衡，最終因衰竭死亡。

二、傳染性疾病：貓瘟與貓傳腹的威脅

幼貓或未接種疫苗的貓咪若吐黃水，需警惕貓瘟（貓泛白細胞減少癥）。這種病毒攻擊腸道和免疫系統，導致嘔吐、便血和高死亡率。貓瘟病程極快，發病48小時內若不通過輸液和抗體治療，貓咪可能因脫水或敗血癥死亡。

貓傳染性腹膜炎（貓傳腹）同樣兇險。病毒引發腹腔積液和器官炎癥，貓咪初期吐黃水，后期出現黃疸、呼吸困難。盡管近年有特效藥，但確診困難且治療費用高昂，許多貓咪因延誤而喪命。

三、中毒與器官衰竭：不可逆的傷害

誤食百合、清潔劑或人類藥物會導致貓咪中毒，毒素直接損傷肝臟和腎臟。中毒后嘔吐黃水是典型癥狀，若不及時洗胃或注射解毒劑，可能引發多器官衰竭。

慢性疾病如腎衰竭或脂肪肝也可能表現為吐黃水。例如，老年貓腎臟功能衰退時，體內毒素堆積刺激胃腸，嘔吐后迅速惡化至尿毒癥。這類疾病早期癥狀隱蔽，發現時往往已到晚期。

四、緊急處理與日常預防：為生命爭取時間

發現貓咪吐黃水時，三步關鍵應對：

1. 立即禁食禁水，避免刺激腸胃；

2. 觀察伴隨癥狀，如精神萎靡、腹瀉或體溫異常；

3. 24小時內送醫，通過血常規、B超等檢查確診病因。

日常預防措施：

飲食定時定量，避免喂食生肉、高脂肪食物；

定期驅蟲和接種疫苗，降低寄生蟲與病毒風險；

提供貓草或化毛膏，每周梳理毛發減少毛球堆積。
