Some hamsters die because of illness or disease, such as Wet Tail Disease while others pass away due to preventable mistakes such as falling from a dangerously high height.

Hamster behavior can be confusing at times. Is my pet just burrowing? Just hiding away to hibernate? Maybe they’re sick and require a trip to the vet? Although hamsters do have a shorter lifespan than most household pets, if you take care of your hamster and watch for signs of illness, they can live a healthy and happy life. Here’s how to do just that.

Why Do Hamsters Die: Common Hamster Illnesses

Just like any other living creature, hamsters can get sick and die. The cause can be a bacterial, viral or fungal infection. When these are left untreated – and sometimes even with the best veterinarian care – they are able to sometimes be fatal.

Prevent Infections From Spreading

Hamsters easily spread disease amongst each other, so if you have more than one hamster in a habitat and think 1 might be sick, you should separate them right away.

It’s very common for hamsters to burrow and hide in their habitat. Either way, none of us wants to see our pet unwell. This infection can result in an abscess and may be extremely painful for your pet, requiring drainage and antibiotics. For a more detailed coverage of these and other ailments, make sure you read our guide about the 7 health issues in hamsters that every owner needs to know about.


We love to coo over hamster with chubby cheeks, commenting on how adorable their little faces look.

But there are occasions when those puffy cheeks are a cause for concern. If you notice your hamster has a wet nose, having difficulty breathing, or is wheezing, a cold might be the culprit.

With that in mind, here are a few common hamster illnesses that, if left untreated, can result in death. If you notice swelling or a lump, hard or soft, anywhere on your hamsters’ body, it’s necessary to visit a veterinarian immediately.

Left untreated, the bacteria which causes the abscess can get into the hamster’s bloodstream and cause a dangerous condition called bacteremia. Since the hamster’s body is so small, once bacteremia sets in, there’s usually no going back. That’s why you should not delay treatment – get your hamster to the vet as soon as you notice any lumps.

Cough And Colds

It’s surprising for many people to learn that a hamster can catch a cold, just like me and you!

The little critters can develop the sniffles, sneezing, or even have a cough.

Your hamster can develop an infection, caused by bacteria.

But, even though a cough is relatively harmless for humans, a respiratory infection can lead to a far more serious illness in your hamster. If you believe your pet has a cold, it’s best to consult with a medical professional for advice on how to treat and keep your hamster healthy. In other words, yes, your hamster needs to be seen by a qualified veterinarian.

Wet Tail Disease

Triggered by bacteria and stress, wet tail disease is unfortunately very common among hamsters and is highly contagious.

Sadly, even if caught early, most wet tail disease diagnoses end in death with 72 hours. If you notice your hamster has diarrhea, unexplained wetness around the tail, low energy, fatigue, or aggression, it is critical to seek medical attention for your pet as soon as possible.

Your veterinarian can accurately assess your hamster and discuss the next steps of care, or prescribe antibiotics if required.
