Why Hamsters Die (Main Reasons, Some Of Them Preventable)

Hamsters can die, and it’s never pleasant news to hear your little friend passed away. But why did that happen ? Was it old age ? Was the hamster suffering from an illness or an injury ? Let’s see what the most common causes are.

So why do hamsters die ?

Hamsters can die for a number of reasons, and it’s usually a medical condition. Even old hamsters, very old ones, pass away because their bodies simply don’t function as well as they used to, and some critical part of their body no longer works.

Sometimes, hamsters can die of diseases or injuries, most of them preventable. Not all are noticeable. Or, if you do notice, you don’t figure out what the problem is until it’s too late.

Knowing the usual health problems hamsters can get, and what old age looks like for hamsters will help you know when and if there is anything left to do.

When is a hamster considered old ?

Usually a hamster is old by the time he reaches 2 years of age. In Chinese hamsters this threshold is lower, since their average lifespan is 2 years. So they can be considered old by the time they reach their first birthday.

Most hamsters live 2-3 years, and as such you’ll notice the changes happening to then when they get old fairly quickly.

Sparse fur, weak legs, cataracts, a withered look about them, a distinct neck – these are all clear signs your hamster is a senior in his right.

Along with old age come a host of health problems, mostly because it’s easier for them to come along. Like wet-tail for example, which can be brought on either by stress or an infection. An infection happens easier if the hamster is not clean, and a very old hamster will stop grooming himself as much.

So, an old hamster who develops wet-tail has very little chances of survival, and his death could be attributed to both the disease and the old age.

Old age also makes the immune system weaker, and the body weaker overall. Bones don’t mend as easily, sores don’t go away. Any injury to an old hamster is harder to heal than one to a young hamster.

Health problems hamsters can commonly get

Most health problems can be avoided, like infections, overgrown teeth, cuts and scrapes, injuries from falling and so on. They can also be easily treated with the help of a competent veterinarian. You will need to look for an ”exotics” vet, who will have experience with rodents, reptiles, and birds as well.

Antibiotics will take care of infections. Tumors can be removed most of the time. bones can be mended, But there are some diseases or problems that can be… well, deadly. Especially so if not noticed in time and treated. Let’s go over a few of them.

Wet-tail is the first to spring into mind. It’s a sort of digestive problem, with symptoms like diarrhea, excessive water drinking, loss of appetite, a sweaty/wet look, a soiled wet hamster bottom, possibly smelly cage. Can be lethal in less than a week if left untreated.

If treated within 24h of developing, it can be survived. Longer than that. and the chances are lower. Even after treatment some hamsters still pass away, because they were too drained from the illness itself. It took a huge toll on their bodies and they withered away.

Any sort of infection, if it’s not treated right away. By this I mean the infections filled with pus, whether it’s an infected tooth, eye, or ear. All of them can spread to the brain, and inside the body. If the hamster swallows the pus (in the case of an infected tooth or cheek) this can lead to sepsis, which too can be fatal.

Lumps and tumors can be deadly as well, mostly because they can be very hard to operate on. The hamster, being so very small, has little chance of surviving anaethesia, although there have been cases.

In some cases the tumor is inside the body, and removing it is sentencing the hamster to certain death, with blood loss as the main cause. The surgery would be too big of a risk, again. Chemotherapy is hard to survive even for humans, let alone for hamsters.

Injuries, like a broken spine because of a nasty fall, can be deadly too. While a fall from the height of an ordinary table isn’t much for a human, it can be deadly for a hamster. Keep in mind that they’re so very small, and have a fragile frame.

This means that falls from heights like your table, dresser, even just your hands while you stand up, can all lead to serious injuries and sometimes even death.

Those falls can be deadly either on impact, like a fractured skull, or serious internal organ injuries, and they can also be deadly by result. Like internal bleeding, ruptured organs, and so on. It’s a terrible thought to write about, so please handle your hamster very carefully.

When it comes to bedding, and textiles introduced to your hamster, be careful. The extra fluffy, puffy kind of textile sometimes found on or in hamster toys (the ones with very long fibers, like the stuffing inside teddy bears). That is dangerous for hamsters, since they will find it and stuff it in their cheeks, and use it as nesting material.

While it does keep them warm, it’s also too easy for them to tangle that material in their teeth or cheeks, or get a foot stuck inside, or in some cases pretty much wrap it around their necks and suffocate.

I’m sorry to paint pictures like these, but this has happened before to other hamster owners. Please keep plush and overly fluffy things far away from hamsters.

As a sidenote, I have a blanket with a plush side. When I let Teddy onto the bed one day and the blanket was there, he immediately started putting it in his cheeks. They’re very fast, and you need to spot them right away to stop them.

Finally, there is another reason for hamsters seeming to suddenly die. Some people have reported their hamsters being happy and healthy yesterday, only to find them lifeless this morning.

Those cases, while unfortunate and traumatic, always have an explanation. Most of the time, it’s a circulatory problem. Like a blood clot forming in the brain, or a form of heart attack brought on by a scare in the middle of the night.

Hamsters are very sensitive, and scaring them too hard is … well, easier than necessary. This is one reason you should not scare your hamster, or let it get too stressed.

Being barked at, handled too often, dangled upside down, continuously poked and prodded and so on. These are very stressful things for a hamster, and can be the final straw in some cases.

Do not confuse hibernation with hypothermia

I’ve set this one aside because it’s a common problem. Hamsters do hibernate, but only in the wild. In the wild, they have a weeks and months in advance to prepare for the cold. Gather food, get fat and have energy stored up, dig a big warm nest, get safe.

They go to sleep once winter comes and they only wake up from time to time (like once a week !) to nibble on something they’ve stored up. When they wake up, the earth is thawing, they’re hungry and dehydrated.

At home, in your warm house, the cold doesn’t gradually creep in over the span of a few months. It never does, because you keep your home warm.

So why do some hamsters end up ‘hibernating’ ? Well, they’ve sometimes been left out in the garage for a few hours, or another such space that’s used for storage and is usually cold. Or they were maybe forgotten next to an opened window. Really, it could be any occasion with cold temperatures.

The point is that the hamster will go into a sort of hibernation, but in truth it’s actually hypothermia. He did not have time to build an extra warm nest, build a protective layer of fat on his body, but he did store some food. The problem is that this is not true hibernation, and he will likely die if not woken up fast.

You might think he is dead, be might be cold. He might not move at all. But a dead hamster will be rigid, like a statue. He will be cold. A hibernating hamster will be cold-ish, but his whiskers or ears might twitch if you touch them. He will be limp, that’s the first major sign he is alright.

For more info on waking up a hamster from such a situation, check this article. Always, always attempt to warm him up or wake him before deciding he has passed away.

There have been accounts of hamsters thrown away in the trash bin, only to be found by the garbage disposal service later, alive and kicking.

Making sure you keep your hamster safe

There are ways your can make sure your hamster lives a happy, healthy life. Now, although what I explained above might make you want to keep him under a glass dome, don’t do that.

Instead, be a responsible hamster owner and keep him out of trouble. Let’s see what that means:

• Keep the hamster away from overly curious pets who might disturb him, like a cat or a puppy or even parrots or other rodents. Basically any pet that can move through the house on its own.
• Always supervise kids playing with the hamster. Accidents can happen, and it’s your responsibility to both teach the child and keep the hamster safe.
• Only handle the hamster close to his cage, and not allow more than double his height as a falling height.
• If you’re letting the hamster onto the floor, make sure there are no places for him to get inside or under or between pieces of furniture and be impossible to get out safely.
• Keep any fluffy textile or materials away from your hamster. Some are sold as nesting material. Stay away from them.
• Never overfeed your hamster, else he might grow obese and develop diabetes and joint problems.
• Be careful which foods from your fridge or pantry you feed you hamster. Some are safe, some not.
• Always clean his cage, once a week, a full cleaning complete with a cage wipe-down or actual rinsing on the shower.
• Make sure you bring your hamster to the vet, even if it might be nothing. Better to have him checked and find out he’s okay, than leave it to chance and figure out there is a problem when it’s too late.

Thees are the absolute basics of keeping your hamster healthy and safe, more info can be found in the related articles below. Until then, read Teddy’s thoughts on the matter.

A word from Teddy

I hope you found what you were looking for in this article. Us hammies are cute and cuddly, but we do pass away. That means we’re sometimes too sick, or we grow too old to fight an injury or sickness. We rely on you to spot the problem and help us out.
