Why is My Hamster Trying to Kill Itself?

Well, hamsters are not suicidal at all. But what they do is make dangerous mistakes. And there are no come back after that. Generally, this happens when a hamster is old age, feels bored, loses its eyesight, and causes other physical damage.

So, keeping a hamster happy and healthy is the most important thing- you can already guess. 

Reasons Behind Sudden Death of A Hamster

Hamsters are sensitive animals in nature. Both wild and pet hamsters have the same behavior and habit. They actually do not like to get along with other animals. They like to stay alone, and that’s the start of some problems. Let’s see what the reasons are behind the sudden death of a hamster.


Hamsters who have already passed a certain beautiful time of their life, start having many issues. That doesn’t mean they intend to die at once. But we can assume that they start losing interest in everything as they get older. Maybe they get a heart stroke discreetly and die.

Bad Eyesight

Hamsters lose their eyesight too quickly than other animals. Losing eyesight, they become weaker than usual. They are prey animals, so they need all their senses to survive. If their vision starts to become blurry, they get scared easily. They don’t know where they are going, and in doing so, they die!


Though hamsters don’t show stress or boredom as rabbits or guinea pigs do. But still, sometimes they feel stressed. You may have seen them biting the cage, making sounds, tossing around, and kicking their sandbox. These are the signs of stress. Being stressed, sometimes they make some serious and dangerous mistakes which lead them to death.


Yes, a common rare disease in hamsters is diabetes. These cute animals suffer the same as humans. They get so thirsty often and pee a lot. They lose their weight, and sudden death is not an abnormal issue. However, there are certainly some ways to provide them with a better diet to balance diabetes.


Neoplasia- cancer in hamsters, is fatal. From the skin to the gastrointestinal tract, this cancer can affect them. If you notice your hamster is losing its hair suddenly and is also losing some of its weight rapidly, then consider it cancer. However, cancer is not a very common disease in hamsters.

Heart Disease

Hamsters get random heart diseases when they start getting older. As they age, their heart muscle starts being weaker than before. This is the time when heart failure happens in hamsters.


Another common disease in hamsters is diarrhea. Hamsters like to have food where they stay. For that, they start making their food and place messy. This is harmful to their digestive system, and they get diarrhea.

Can Hamsters Run Themselves to Death?

Yes, your hamsters can die while running. We all know hamsters like a wheel to run. They can keep running and running almost all day long. Though they find happiness while running and this is kind of a game to them, but still it’s dangerous if they run over the limit.

A dehydrated and weak hamster should never run at all. Sometimes the hamster can not understand the limit and overdo it. And that’s an ending for him! So, what to do? Don’t feel scared. Surely we can help our hamsters here.
