Watch his diet

Hamsters will eat anything they like, they won’t know if something is toxic or not, so we have to pay attention to their nutrition.

Although we sometimes do not know that some food is toxic to hamsters because we can eat it. Cyanide is a dangerous toxin that can seriously harm a hamster and is found in bitter almonds and apple seeds.

There are other foods that are toxic and dangerous for hamsters, here are some:

  • garlic – causes blood problems in hamsters
  • onion – just like garlic creates blood problems
  • sweets – have too much sugar
  • salt – is harmful and causes diseases in hamsters
  • citrus – too much acid that will make the hamster sick
  • cyanide – can kill the hamster

How do we know that hamsters have swallowed something bad?

In order to prevent problems or choking of hamsters because they cannot throw up, we need to know what the symptoms are when they have eaten something that is dangerous and harmful for them.

Drinking too much water

Another sign is that the hamster is not feeling well when drinking a lot of water because there may be toxins in the body.

The only way to flush out toxins is water which helps the kidneys and liver fight against the toxic substance.

He doesn’t mind the fur

Hamsters always take care of their fur and groom themselves.

If your hamster stops doing this, it means that it is sick, it may have toxins in its body, and therefore it is not paying attention to its fur.


When the hamsters are healthy, they constantly run and play in the cage, on the wheel, and in general, do something all day long.

But if the hamster just sits in the corner of the cage or hides, then something is wrong with it, and there may be toxic substances that disturb its health.

These are just some of the signs, and there are others that indicate that something is wrong with the hamster, that there may be toxins in the body, and it cannot recover them, and we should immediately take it to a veterinarian to examine it.

We must say again that hamsters cannot throw up, and they are in danger of choking on food.

When hamsters eat large pieces of food they can choke.

If you feed them store-bought food for hamsters, there probably won’t be a problem because it’s already cut into pieces so they can’t choke.
