今すぐやるべきこと
- 1
Step 1: Remove All Chocolate Immediately
Cats are naturally curious but also more sensitive to toxins. Remove any remaining chocolate from their environment.

Step 2: Call Poison Control or Vet
📞 ASPCA Poison Control: (888) 426-4435. Cats are more sensitive to theobromine than dogs — small amounts are concerning.

Step 3: Do NOT Induce Vomiting Without Vet Approval
⚠️ Cats may hide symptoms until severe. Inducing vomiting risks aspiration. Only do so if instructed by a veterinarian.

Step 4: Go to Vet for Cardiac Monitoring
Your vet may recommend induced vomiting (if early), activated charcoal, and ECG monitoring to watch for arrhythmias.
その背後の科学
チョコレートにはテオブロミンとカフェインが含まれており、これらは猫が効率的に代謝できないメチルキサンチンです。ネコ科動物の肝臓のサイトクロムP450酵素の活性は犬よりも低いため、テオブロミンの半衰期が長くなります。これにより、CNS（発作）、心血管系（不整脈）、平滑筋に蓄積的な影響を及ぼします。また、猫は植物由来のアルカロイドを処理する能力が低い専食性肉食動物です。体重が小さく、代謝が遅く、感受性が高いという組み合わせにより、チョコレートは猫にとって比例的に危険性が高くなります（ASPCA、2023）。
よくある質問
Is chocolate toxic to cats?
Yes, chocolate is toxic to cats — often more so than to dogs relative to body weight. Cats are more sensitive to theobromine because they metabolize it more slowly. The same toxic principle applies: theobromine and caffeine cause CNS stimulation, cardiac arrhythmias, and potentially seizures.
Why are cats more sensitive than dogs?
Cats have lower activity of cytochrome P450 enzymes responsible for metabolizing theobromine. While dogs take 17+ hours to clear theobromine, cats may take even longer. Additionally, cats typically weigh less (4-6kg average), so the dose-per-kg ratio from the same amount of chocolate is higher.
How much chocolate is toxic to cats?
Milk chocolate becomes toxic at approximately 0.5 oz per pound of body weight. Dark chocolate and baking chocolate are 2-5x more toxic. For a 5kg (11lb) cat, as little as 20g of milk chocolate (about half a standard bar) can cause symptoms. Baking chocolate is lethal at 5-10g for an average cat.
What should I do if my cat ate chocolate?
Call ASPCA Poison Control at (888) 426-4435 or your vet immediately. Cats are more sensitive than dogs — even small amounts are concerning. Bring the chocolate packaging to identify theobromine content. Do NOT wait for symptoms, as cardiac arrhythmias can be sudden and fatal.
