What are the effects of chocolate on cats?

Chocolate contains methylxanthines β€” substances that may be deadly for cats. Smaller amounts of chocolate may cause symptoms that include:

  • Vomiting and diarrhea;
  • Rapid or irregular heartbeat; and
  • Tremors or seizures.

How long before symptoms of chocolate poisoning in cats occur?

Signs and symptoms of chocolate poisoning in cats usually start within 4 hours of chocolate consumption. However, your cat should be closely monitored for at least 24 h to make sure that it's entirely ok.

Chocolate poisoning symptoms may last for up to 72 h.

How to calculate chocolate toxicity in cats?

  1. Step one: gather data.

    • Find out your cat's weight.
    • Measure exactly how much chocolate is missing.
    • Ask Google about the amount of methylxanthines present in your type of chocolate (look for sites with nutritional information).
  2. Step two: calculations.

Our cat chocolate toxicity calculator uses the following equations:

Theobromine dose = (Chocolate type * Amount eaten) / Weight

Caffeine dose = (Chocolate type * Amount eaten) / Weight

Total dose = Caffeine dose + Theobromine dose

where:

  • Theobromine dose and Caffeine dose are given in mg/kg.
  • Chocolate type means the concentration of theobromine/caffeine in 1 g of a given chocolate product.
  • Amount eaten β€” Given in grams (g).
  • Weight of the pet is given in kilograms (kg).

To evaluate the total toxicity, we need to use the Total dose that we've already calculated:

  • A total dose of <15.01 mg/kg β€” your cat's going to be ok.
  • A dose between 15.01-34.02 mg/kg β€” your pet may suffer from diarrhea and vomiting.
  • A dose between 34.02-45 mg/kg β€” your feline may also suffer from tachyarrhythmia (possibly dangerous, rapid heartbeat).
  • A dose between 45-55.01 mg/kg will cause seizures and tremors.
  • A total dose larger than 55.01 mg/kg may kill your cat.
