How long does it take a hamster to die after eating chocolate?

A hamster that eats chocolate can die very quickly from the effects of theobromine.

How quickly the hamster will die depends on the type of chocolate it ate, the amount, as well as the size or breed of your pet.

Theobromine is the main ingredient in chocolate that causes death in hamsters and is in most amounts in dark chocolate.


Theobromine is an ingredient that is found in large quantities in chocolate, especially dark chocolate.

When theobromine is introduced into the body of hamsters, it is metabolized very slowly, that is, it breaks down slowly and accumulates and becomes toxic for them.

Even very small amounts of theobromine can be harmful to their health and can cause fatal consequences or death.

It only takes a few hours for the theobromine to start working after the hamster eats the chocolate. Hamsters’ heart rate starts to increase, and they become nervous and have seizures.

The most dangerous moment is when, due to theobromine, hamsters get problems with the respiratory system and cardiac arrhythmias, which can be fatal and kill the hamster.

Everything depends on the amount of chocolate or theobromine that the hamsters will take into their body, the hamsters can have milder or more severe symptoms that can end fatally.

What types of chocolate are the most dangerous for hamsters?

All types of chocolates are harmful to hamsters, but some have more and some less theobromine.

Here are the chocolates that contain theobromine:

  • cooking chocolate 400-450 mg/oz
  • dark chocolate 150-450 mg/oz
  • milk chocolate 45-60 mg/oz
  • white chocolate in minor amounts

This is approximately how much theobromine various types of chocolate contain and may vary depending on the brand of chocolate.

Baking chocolate

Cooking chocolate has a massive concentration of theobromine and can be fatal to small hamsters.

Dark chocolate

Dark chocolate has a similar amount of theobromine to cooking chocolate, which is why this chocolate is too dangerous for hamsters.

Also dark chocolate has a very high percentage of cocoa and a high concentration of theobromine that can be fatal to the life of hamsters.

Milk chocolate

Unlike dark chocolate, milk chocolate contains a lower amount of theobromine.

There are more milk ingredients in milk chocolate, but it has a lower amount of theobromine and is less harmful to hamsters.

White chocolate

White chocolate has the least amount of theobromine because it is made from butter, and does not have the solids of cocoa.

But don’t be fooled and give white chocolate to the hamster, because it has a lot of fat and sugar which are again very harmful to the health of the hamster.хow long does it take a hamster to die if it eats chocolate
