Cat Chocolate Toxicity Calculator

Determine if the chocolate your cat consumed is dangerous. Calculate theobromine dose and get immediate action recommendations for chocolate poisoning in cats.

Your cat's weight in kilograms

Amount of chocolate eaten in grams

Theobromine Dose (mg/kg) = (Chocolate Amount × Theobromine Content) / Cat Weight. Toxicity: <20 mg/kg (low), 20-40 (mild), 40-80 (moderate), 80-200 (severe), >200 (lethal). Cats are MORE sensitive than dogs.
4.5kg cat ate 30g milk chocolate: 30g × 2.4mg/g = 72mg theobromine. 72 ÷ 4.5 = 16 mg/kg (Low risk, monitor). Same cat ate 20g dark chocolate: 20g × 5.5mg/g = 110mg. 110 ÷ 4.5 = 24.4 mg/kg (Mild toxicity - CALL VET).

Is chocolate more dangerous for cats than dogs?

Yes! Cats are MORE sensitive to theobromine and caffeine than dogs. Cats also typically weigh less, so smaller amounts are more dangerous. Additionally, cats are obligate carnivores and cannot metabolize these compounds as efficiently. Even small amounts of chocolate can cause serious toxicity in cats.

What makes chocolate toxic to cats?

Chocolate contains theobromine and caffeine, both methylxanthines that cats cannot metabolize efficiently. These compounds cause: increased heart rate, tremors, seizures, elevated body temperature, abnormal heart rhythms, and potentially death. Dark chocolate and baking chocolate are most dangerous due to higher theobromine content.

What are the symptoms of chocolate poisoning in cats?

Symptoms appear 2-12 hours after ingestion: Early: vomiting, diarrhea, increased thirst, restlessness. Moderate: hyperactivity, rapid breathing, increased heart rate, muscle tremors. Severe: seizures, abnormal heart rhythm, hyperthermia, coma. Time to vet is critical - don't wait for symptoms to worsen.

What should I do if my cat ate chocolate?

IMMEDIATE ACTION: (1) Note chocolate type and amount, (2) Call vet or pet poison hotline immediately, (3) If within 1-2 hours, vet may induce vomiting, (4) Do NOT induce vomiting at home without vet guidance, (5) Bring chocolate packaging to vet, (6) Never "wait and see" - time is critical for treatment success.

How is chocolate poisoning in cats treated?

Treatment depends on severity: Mild: Induced vomiting (if recent), activated charcoal to prevent absorption, IV fluids. Moderate-Severe: Hospitalization, IV fluids, medications to control seizures/tremors, heart rate monitoring, temperature regulation, supportive care. Early treatment greatly improves outcomes. No specific antidote exists.

Can cats die from eating chocolate?

Yes, chocolate can be fatal to cats, especially dark chocolate, baking chocolate, or cocoa powder. Lethal dose: ~200 mg theobromine/kg body weight. For a 4kg cat, this is just 26g of baking chocolate or 145g of dark chocolate. However, serious symptoms occur at much lower doses. Immediate vet care is essential for survival.
