How long do hamsters live?
Two to three years for most pet hamsters. Good sources give slightly different ranges: Wood Green says one and a half to three years, PDSA says about two to three, and the RSPCA says usually up to two, with some living longer. The spread comes from the species. A Campbell's dwarf that lives to two has had a normal life; a Chinese hamster at two is only middle-aged.
That is short next to most pets, so plan for it. You get roughly a thousand evenings with a hamster, and every one of them counts for more than it would with a dog or cat.
Hamster lifespan by species
The National Hamster Council, the UK club for hamster keepers and breeders, gives these figures for each species. PDSA adds that larger species such as Syrians tend to live longer than the smaller Russian dwarfs.
| Species | Typical lifespan | Adult length | Notes |
|---|---|---|---|
| Syrian (golden, teddy bear) | 2 to 3 years | About 13 cm (5.5 in) | PDSA says larger species tend to live longer |
| Chinese | 2.5 to 3 years, some reach 4 | 10 to 12 cm (4 to 4.75 in) | Generally longer-lived than other species |
| Roborovski | 2 to 3 years, some reach 4 | 4.5 to 5 cm (about 2 in) | The smallest, and among the longest-lived |
| Winter white (Siberian) | Average 2 years, 2.5 not uncommon | 8 to 10 cm (3 to 4 in) | Often crossed with Campbell's in shops |
| Campbell's dwarf | Average 2 years | 10 to 12 cm (4 to 4.75 in) | Diabetes is common and shortens life |
Sizes are from the National Hamster Council's species pages and show standards. Our guide to hamster breeds, types and colours covers each species in detail.
How long do Syrian hamsters live as pets?
Usually two to three years. Syrians are the biggest pet hamster, and PDSA notes that larger species tend to outlive the smaller dwarfs. Wood Green says most illness comes with age, and that you should be able to enjoy your hamster without major health worries until about two years old.
Teddy bear, fancy bear and long-haired hamsters are all Syrians with a long coat, so they have the same lifespan. Only the coat is different. The National Hamster Council says only males grow the really long coat, often 7.5 to 10 cm (3 to 4 in), and that longhairs are better without a wheel that could catch the fur, so give them other ways to run, such as a pen.
How long do dwarf hamsters live?
About two years on average, with Roborovskis often living longer. The National Hamster Council gives winter whites (Siberian hamsters) an average of two years, with two and a half not uncommon. Campbell's dwarfs average two years, and the Council says diabetes is common in them and considerably shortens their lives.
Most "Russian dwarf" hamsters sold in UK shops are hybrids of the two, Wood Green notes. The Council asks breeders never to cross these species because hybrids can inherit health problems, which is one reason a dwarf from a good breeder may live longer than a shop dwarf.
Dwarf hamsters are prone to diabetes. Wood Green links it to sugary food and overfeeding, and lists more drinking, more weeing and unexplained weight loss as signs. Keep fruit to a tiny, occasional treat and see a vet if you notice these changes.
How long do Roborovski and Chinese hamsters live?
Two to three years for Roborovskis and two and a half to three for Chinese hamsters, with some of each reaching four, according to the National Hamster Council. That makes them the longest-lived pet hamsters. Chinese hamsters are less common in shops, so you may need to find one through a breeder or a rescue.
Hamster life stages
Hamsters grow up fast. These ages come from the National Hamster Council's breeding notes and code of practice, and from Wood Green's health advice.
| Stage | Age | What is happening |
|---|---|---|
| Newborn pup | 0 to 2 weeks | In the nest with their mother. Pups can be handled from about 14 days. |
| Weaning | 3 to 5 weeks | Eating solid food. Syrian males leave their mother and sisters by 4 weeks. |
| Young hamster | 5 weeks to 6 months | The best time to go to a new home. Club breeders rehome from 5 weeks. |
| Adult | 6 months to 2 years | Full size, settled character, usually the healthiest stretch. |
| Older hamster | From about 2 years | Slower, sleeps more, and illness becomes more likely. |
| Elderly | From about 2.5 years | Thinner coat, long nails, weight loss and lumps are common. |
The Council says hamsters kept together in shops are under 8 weeks old, because after that age they start squabbling. Every adult hamster should live alone, as Wood Green advises for all species.
Signs your hamster is getting old
Wood Green lists the changes you will usually see from around two and a half years.
- Nails growing faster and curling
- Thin or bald patches in the coat
- Sleeping more, and waking later in the evening
- Drinking more
- Lumps and bumps, often on the belly
- Weight loss even though the teeth are fine
- A wobbly walk, or less climbing
- Less time on the wheel
Ageing is natural, but Wood Green advises talking to a vet if your hamster seems to struggle, with the aim of keeping it comfortable and free from pain. Some of these signs, such as weight loss and more drinking, can also mean illness, so it is worth a check rather than assuming it is age. Our guide to hamster health and signs of illness covers what to look for.
How to help your hamster live longer
You cannot change the species' natural span, but you can stop the common things that cut it short.
- Give a big home. Wood Green's minimum is 100 × 50 cm (40 × 20 in) of floor with at least 15 cm (6 in) of bedding. Our hamster cage size guide explains why.
- Use the right bedding. Unscented paper bedding, never sawdust or wood shavings. Wood Green links wrong bedding to fur mites and dusty bedding to breathing problems.
- Feed a good dry mix, and go easy on sugar. About 10 g (a tablespoon) a day for a Syrian and 5 to 8 g (a teaspoon) for dwarfs, Wood Green says, scattered to forage. Our hamster diet guide has the detail.
- Keep the room steady. PDSA advises 18 to 21°C (64 to 70°F). Cold can push a hamster into torpor, which is risky, and heat can cause heatstroke. See our hamster temperature guide.
- Keep it busy. A solid wheel, deep digging, foraging and things to chew. Wood Green says boredom shows as bar chewing and escape attempts.
- Check it every week. Wood Green advises a weekly health check and weighing on kitchen scales. The RSPCA warns hamsters hide pain and lose condition quickly when unwell.
- Find a small-pet vet now. Before you need one, find a practice that sees hamsters often. Wood Green suggests asking how many they see each week.
Write your hamster's weight down every week. A steady drop of a few grams is often the first sign of a problem, long before you would see it by eye.
Caring for an older hamster
Small changes make life easier for a hamster past two.
- Lower or remove high platforms and tall climbing frames
- Keep a water bowl as well as a bottle, so drinking is easy
- Offer softer food, such as a little cooked plain pasta, if it struggles to eat
- Check nails often and ask a vet to trim them if they curl
- Supervise in mesh cages, as Wood Green warns long-nailed older hamsters can get caught in bars
- Keep the routine and room temperature steady
- Feel for new lumps at each health check
Why hamsters die young
Most early deaths come from illness that is noticed too late, stress, or the wrong home. These are the ones our sources name.
| Problem | What to watch for | How urgent |
|---|---|---|
| Wet tail | Watery diarrhoea, a wet, smelly bottom, lethargy, not eating | Same day. Wood Green says it can be fatal within days. |
| Tumours | New lumps, often on the belly | Within a few days. Wood Green says they can grow quickly. |
| Pyometra (females) | Discharge from the genitals, or an older female suddenly dull or unwell | Same day. Wood Green calls it life-threatening. |
| Diabetes (dwarfs) | More drinking and weeing, weight loss | Within a few days |
| Overgrown teeth | Not eating, drooling, weight loss | Within a day or two |
| Torpor from cold | Cold, limp and hard to wake | Warm the room gently and ring a vet |
How long can a hamster live with pyometra?
Not long without treatment. Wood Green describes pyometra, an infection of the womb that is more common in older females, as life-threatening, and says the best treatment is an operation to remove the womb (a spay), because medicine alone is usually unsuccessful. Wood Green's health check says the bottom and genitals should be clean with no discharge, so if an older female has discharge or suddenly seems unwell, see a vet the same day.
When a hamster is very old or ill, a vet can talk you through the options and help you decide what is kindest. It is a gentle decision, and asking early gives you time to make it calmly.
How long can a hamster go without a wheel?
A hamster should not go without one. The RSPCA says wild hamsters can run up to five miles (8 km) a day, mostly at night, and that a pet needs space to exercise every night. A solid wheel of the right size, 30 cm (12 in) for Syrians and Chinese hamsters and 20 cm (8 in) for dwarfs, as Wood Green advises, is the easiest way to give that. A night or two without one while you swap it is fine, but it should never be a long-term gap. Our hamster wheel size guide helps you pick one.
Hamster lifespan: questions
What is the oldest a hamster can live?
The National Hamster Council says some Chinese and Roborovski hamsters reach 4 years, which is about the top of the normal range for a pet. Most hamsters of any species live 2 to 3 years. A hamster past 3 is doing very well, and any age past 2 should be treated as old age.
Do male or female hamsters live longer?
No good source we found gives a clear difference. What differs is the illness risk: older females can get pyometra, a womb infection, and mammary tumours, which Wood Green says are the most common tumour type. Males can get tumours too. Pick on temperament and health, not on an expected lifespan.
How long do hamsters live in the wild?
There is no reliable figure from a welfare or species source. Wild hamsters face predators, cold and food shortages, so we would expect most to live shorter lives than a well-kept pet. The wild Syrian hamster is now rare: the National Hamster Council says it is classed as endangered.
Is a Syrian hamster a good pet?
Yes, for someone around in the evening. Wood Green says Syrians are often easier to handle because of their size, and the National Hamster Council says many become very attached to their owners. They must live alone and need a home of at least 100 × 50 cm (40 × 20 in).
Do Syrian hamsters like to be held?
Many do, once tamed slowly. Wood Green says one to two weeks of calm, patient handling usually gives a hamster that is happy to be picked up and hand-fed. Handle in the evening when your hamster is awake, scoop it in two cupped hands and keep it low over a surface.
How do I keep my hamster from being bored?
Give it things to do every night: deep bedding to dig, a solid wheel of the right size, scattered food to forage, cardboard to shred, a sand bath and hides. Wood Green says swapping toys around keeps a hamster busy, and that constant bar chewing or escape attempts can mean boredom.
