糖果

貓咪可能出現的症狀

由嚴重到輕微排列。

1. 1
   心律不整與心搏過速 2–12 小時（常隨毒素濃度達高峰而惡化） · Methylxanthines from chocolate increase the entry of extracellular calcium into muscle cells, enhancing the strength and frequency of heart contractions4. This can cause life-threatening heart palpitations and cardiac arrhythmias, ultimately leading to cardiac arrest in terminal phases.
2. 2
   嚴重中樞神經抑制（癲癇與昏迷） 進行性（攝入後數小時） · In the later stages of methylxanthine toxicosis (from chocolate candies), the severe overstimulation of the nervous system can progress to grand mal seizures, coma, and respiratory failure.
3. 3
   躁動、活動量異常增加與顫抖 2–12 小時 · Theobromine and caffeine in chocolate candies block adenosine receptors and inhibit the enzyme phosphodiesterase4. This leads to severe overstimulation of the central nervous system, causing the cat to enter a stage of extreme agitation, restlessness, and muscle tremors.
4. 4
   腸胃不適（嘔吐與腹瀉） 通常在攝入後 2–12 小時內 · This is typically one of the earliest signs of chocolate (methylxanthine) poisoning12. Very high levels of artificial sweeteners like xylitol, or general sugar overload, can also trigger general tummy upsets and loose stools.
5. 5
   過度口渴與排尿增加 2–12 小時 · Theobromine acts as a mild diuretic, causing the cat to lose bodily fluids and triggering excessive thirst and urination as the chemical stays in the bloodstream.
6. 6
   暫時性流涎 攝入後不久 · In experimental studies evaluating the effects of xylitol (found in sugar-free candies and mints) on cats, massive oral doses caused no significant changes in blood sugar or liver parameters, with transient salivation being the only reported clinical sign.

重要提醒

市售的糖果不一定對貓咪直接有毒，但常帶有多重間接風險，因此不太適合給貓吃。主要問題是高糖分，容易造成腸胃不適。巧克力口味糖果含有可可鹼和咖啡因等甲基黃嘌呤，對貓高度有毒。無糖糖果可能含有木糖醇。此外，硬糖有噎住風險，鋁箔或塑膠包裝也可能造成腸道阻塞。

• 巧克力口味糖果：即使少量也可能造成甲基黃嘌呤中毒，包括嘔吐、躁動、肌肉顫抖與心律不整。
• 高糖分：幾乎都可能造成滲透性腹瀉與腸胃不適。
• 包裝紙：不易通過腸道，可能造成需要手術處理的阻塞。
• 處理方式：所有糖果都應妥善收好，避免貓接觸。如果吃到巧克力口味糖果，應視為甲基黃嘌呤中毒急症並立即聯絡獸醫。
