Use this cat chocolate toxicity calculator helps determine the severity of chocolate poisoning based on your kittens’s weight and the type/amount of chocolate consumed.
For example, if your 4kg cat consumes 15g of dark chocolate, the calculator considers the theobromine concentration (the toxic compound) to assess risk levels.
Different chocolates contain varying levels of theobromine:
- Dark chocolate: ~450mg/oz
- Milk chocolate: ~150mg/oz
- White chocolate: ~1mg/oz

Cat Chocolate Toxicity Formula
The formula used is:
Toxicity Level = (mg of theobromine per oz × oz of chocolate consumed) ÷ cat's weight in kgExample calculation:
For a 4kg cat eating 0.5oz dark chocolate:
(450mg × 0.5oz) ÷ 4kg = 56.25mg/kgHow much chocolate is toxic for a cat?
Cats can experience toxicity at much lower doses than dogs. Mild toxicity begins at around 20mg/kg of theobromine.
For perspective, a 5kg cat would show symptoms after consuming just 2-3g of dark chocolate.
Clinical example: A 3kg cat consuming 1oz of milk chocolate:
(150mg × 1oz) ÷ 3kg = 50mg/kg (Moderate toxicity)How much chocolate can kill a cat?
The lethal dose of theobromine for cats is approximately 200mg/kg. This means a 4kg cat could face life-threatening complications from consuming about 20g of dark chocolate or 60g of milk chocolate.
What if my cat ate a little bit of chocolate?
Even small amounts warrant attention. If your cat consumes chocolate:
- Document the type and amount eaten
- Note the time of ingestion
- Contact your veterinarian immediately
A 6kg cat eating 5g of milk chocolate might not show severe symptoms but should still be monitored.
What is the antidote for chocolate poisoning in cats?
While there’s no specific antidote, treatment includes:
- Activated charcoal administration
- IV fluid therapy
- Anti-nausea medication
- Heart rate monitoring
How long does it take to get symptoms of chocolate poisoning in cats?
Symptoms typically appear within 2-12 hours post-ingestion and can last up to 72 hours. Early signs include:
- Restlessness (2-4 hours)
- Vomiting (4-6 hours)
- Increased heart rate (6-8 hours)
- Seizures (in severe cases, 8-12 hours)
