What ingredients are poisonous to hamsters ?

Chocolate has two poisonous ingredients in it. To name them, they include theobromine, caffeine, etc. You might wonder as to why chocolate is safe for us but not for the hamsters. In fact, it is these two elements that result in the toxicity of the hamsters. One element is a stimulant, and the other is an alkaloid. So, let’s dig deep into this and see why these ingredients are toxic for hamsters.


Theobromine is a harmful ingredient contained in chocolate. In fact, this is the most harmful ingredient in chocolate. It is more like an alkaloid compound, which would usually arise from the cacao plant itself. Chocolate is made from the cacao plant. However, theobromine will not have any negative impact on humans as long as you consume it in moderation. For example, it would help reduce blood pressure levels among humans.

Additionally, it would help humans sleep better as well. Apart from that, it would also be effective on lung function as well. Furthermore, it can also function as a mild stimulant, which would help humans improve their focus and concentration. Suppose that you consume too much chocolate, then the worst repercussion you may come across would only be a headache. Further chances are that you may experience some trembling and sweating. The human liver has a high metabolism towards theobromine. So, it is very unlikely that it will do any harm even if you consume them in excess.

On the other hand, hamsters’ livers are small when you compare them with a human’s liver. As such, they will have a slower metabolism compared to humans. This is exactly why even a smaller amount of chocolate would turn out  to be unhealthy and toxic for the hamsters.

If your hamster suffers from theobromine poisoning, you could see them urinating quite often. It is one of the most frequently spotted symptoms of theobromine poisoning. As time passes, you can see how they develop irregular heartbeats and seizures too. Further chances are that they may also suffer from internal bleedings. Lastly, it may also result in heart attacks.


Caffeine is also a harmful substance for hamsters. However, it won’t be as harmful as theobromine. Caffeine is a stimulant that you can find in chocolate. Caffeine is very beneficial for the nervous system, as it helps us stay focused and be more productive. Having said that, if we happen to have too much caffeine, it will make us suffer from insomnia and anxiety. Further chances are that it could also cause digestive related issues.

If we consider the hamsters, a little amount of caffeine would cause changes in the pulses, which would sometimes turn out to be life threatening. The combination of theobromine and caffeine can do greater damage to the hamsters. It is noteworthy that they would turn out to be fatal as well. To sum up, the two ingredients that would cause the toxicity of the chocolate for hamsters are theobromine and caffeine.

Why can’t hamsters eat chocolate?

In addition to that, you could see them urinating quite often too.
