In that case, it’s a good idea to know how long that lifespan is and how that compares to the lifespans of other types of hamsters.

The Roborovski dwarf hamster is the hamster type with the longest lifespan of the common pet hamster breeds. It can live up to four years. Even so, this breed’s lifespan still only averages around three and a half years.

You may wonder what the average lifespan of hamsters, in general, is to help provide a frame of reference. Hamsters typically live between two and three years, meaning the average lifespan of the Roborovski is only about a year longer than other hamster types.

While this is a significant difference, it’s important to remember that these are just averages, and your pet may live significantly shorter or even longer than these projected estimates.

Furthermore, other elements besides lifespan should be considered when choosing a hamster, especially if you’re looking for a pet for a young child, where temperament will also be an essential factor.

Syrian Hamsters Are the Most Common Pet Hamsters

Average size: four to seven inches (10.16 to 17.78 cm)

Average lifespan: two to two and a half years

The Syrian or golden hamster is the most common breed found as a pet. It makes a great pet because it’s easy to handle and socialize with humans. Plus, this hamster is of a manageable size.

These hamsters are larger than many other hamster breeds, especially males. Because of this, it’s easier for you to hold and keep track of them during playtime.

Syrian hamsters are nocturnal and mostly sleep throughout the day. Because of this, they should be fed and interacted with mainly in the evenings, when they’re naturally awake and ready for stimulation.

As they get older, Syrian hamsters become highly territorial. You shouldn’t house them with other hamsters, even their littermates. These hamsters can kill each other if cohabiting, so make sure only to have one Syrian hamster and give it plenty of stimulation and company.

Roborovski Dwarf Hamsters Are Best for More Experienced Owners

Average size: roughly two inches (5.08 cm)

Average lifespan: three to four years old

Roborovski dwarf hamsters have the most extended lifespan of the domesticated hamster breeds, and an exceptionally healthy hamster can live for up to four years.

However, it’s essential to keep in mind that many factors impact the lifespan of hamsters, and if cared for properly, many hamster breeds can make it to three years old.

Roborovski dwarf hamsters are the smallest domesticated hamsters and are quite jumpy and difficult to handle.

The difficulty owners face handling this type of hamster is due to its high agility, more so than its sociability. While friendly with people, Roborovski dwarf hamsters are known to get lost easily, and even experienced handlers can have difficulty holding onto these little furballs.

Because of this, Roborovski dwarf hamsters are recommended for more experienced hamster owners. Most time spent with your hamster should be in their habitat or an area where they can’t escape and get lost under furniture or other items.

Like Syrian hamsters, Roborovski hamsters tend to get more territorial as they grow up, but you could potentially have success co-housing two same-sex hamsters as long as you pair them very young. 

You’ll want to make sure they have plenty of room to keep them happy. Keep an eye on them for any signs of conflict. Be prepared to separate your hamsters if you notice territorial behavior between the two.

Campbell’s Russian Dwarf Hamsters Aren’t Very Territorial

Average size: roughly four inches (10.16 cm)

Average lifespan: one and a half to three years

Campbell’s Russian dwarf hamsters are another hamster breed better for a more experienced hamster owner. These hamsters are typically less handleable and sociable with people compared to Syrian hamsters but still make excellent pets when given time to acclimate.

Slightly more shy and nervous, Campbell’s Russian dwarf hamsters have a track record of biting more than other breeds, and thus, should be supervised when interacting with children.

However, once comfortable, these hamsters bond with their owners and may still be acceptable with young children they’re given time to get to know. Consider encouraging your child to wear gloves when handling their hamster until the hamster has gotten used to them.

These hamsters are significantly less territorial than other breeds of hamsters and tend to do well with same-sex pairings.

Average size: roughly four inches (10.16 cm)

Average lifespan: one and a half to two years

While nocturnal, Chinese hamsters tend to be slightly more active during the day than other hamster breeds, making them fun pets. Just be sure to allow your hamster to dictate when you interact during the daytime, as rest is essential to its mental and physical well-being.

Chinese hamsters are slightly more timid than other hamster breeds but still make OK pets for hamster owners that are experienced and patient. These hamsters are known for their thin, long bodies and are often confused with mice at first glance.

Like Syrians, Chinese hamsters should never be housed with other hamsters, as they’re very territorial of their space.

Winter White Russian Dwarf Hamsters Are Small and Agile

Average size: three and a half to four inches (8.89 to 10.16 cm)

Average lifespan: two years

Winter white Russian dwarf hamsters are small and very agile, like Roborovski hamsters. Because of this, they’re not recommended for first-time hamster owners.

They should be housed in a terrarium with glass walls and a mesh topping, as their small size and agility make it possible for them to squeeze through many wire cages with larger openings.

These hamsters have somewhat of a reputation of jumping out of their handler’s hands and getting lost, so use caution when handling your winter white hamster.

This hamster breed does well with same-sex pairings, so consider getting a friend for your young winter white Russian dwarf.

What Type of Hamster Has the Shortest Lifespan?

If you’re a first-time hamster owner and learning more about Roborovski hamsters has made you question whether a different breed may be a better fit, you may be left wondering which type of hamster has the shortest lifespan.

The Chinese dwarf hamster has the shortest lifespan of commonly domesticated hamster breeds, with an average lifespan of just shy of two years. Also typically living for about two years is the winter white Russian dwarf hamster.

While this might seem like an extremely short lifespan, remember that the average hamster lifespan across all breeds is only two to three years.

Furthermore, multiple factors can affect the lifespan of pet hamsters, including diet, habitat, exercise, and genetics. While some hamsters can’t escape their genetic makeup, most hamsters can live toward the high end of their predicted lifespan when cared for adequately.

Ensuring that you’re feeding your hamster a high-quality diet and giving it appropriate mental and physical stimulation is crucial to its well-being.

Additionally, ensuring your hamster has an appropriately-sized habitat that’s kept clean is essential for their health.
