Hamster Facts: Learn Interesting Things About Pet Hamsters

For some people, hamsters are the perfect pet!

They are nice to look at and entertaining to watch, soft and cuddly to hold, fairly independent, and don’t take up a lot of space, which makes them great starter pets for children.

However, they do need regular cleaning out – which can be a messy job – and only live for a few years.


In this article we will look at what hamsters are, describe different breeds and discover some interesting hamster facts.

What is a hamster?

Small animals, hamsters have small furry ears, stocky legs with wide feet, thick and silky fur, and short tails.

Even Chinese dwarf hamsters, who have the longest tails among hamsters, still have quite small ones.

Why do they have such short tails compared to other rodents?

The reason for this is probably because hamsters evolved to be burrowing rodents and having a shorter tail helps them burrow more quickly.

It is also less likely to be grabbed while they are trying to evade a predator.

They are not climbers, like some other small animals, such as rats or mice, where a long tail helps them balance as they go in search of food, a nest and to avoid predators.

Lifestyle and behavior

Hamsters are nocturnal, which means they sleep during the day and are active at night.

A hamster’s natural habitat in the wild consists of warm, dry areas such as steppes and the edges of deserts.

They are omnivores choosing to mainly eat seeds, plants and insects.

Hamsters have some peculiar mannerisms, such as stuffing their cheeks, grinding their teeth, stretching their legs and suddenly freezing in place.

If you are curious to know why they do these and other things, then here is a lovely little article offering some explanations…

Common breeds of pet hamster

Hamsters are really popular pets, but even though there are over 20 species, only 5 make good pets.

All other hamsters continue to live in the wild.

While limited to a choice of 5, pet owners will not be disappointed with the options they have and will have no problems finding a great pet.

Here are the 5 breeds of this popular pet…

Syrian hamster

Length 4-6 inches
Weight 5 ounces
Lifespan 2-4 years
Temperament Easy to handle, curious, territorial


Also known as golden hamsters and teddy bear hamsters, these beauties hail from northern Syria and southern Turkey.

Most have a golden brown coat with a lighter colored belly.

Perhaps the most important thing to note about Syrian hamsters is that they must live on their own.

This breed are solitary animals and will fight ferociously with each other.

Even having another Syrian hamster in a different part of the house could be problematic as if they smell each other they might become upset.

Keeping other hamsters – i.e. different breeds – is fine, though.

Around humans, however, they are delightful animals and make very good pets.

They are happy to be handled, but are also curious so would prefer to scurry up your arm and sit on your shoulders rather than sit quietly in the cup of your hand.

Do they like to play?

Absolutely, they do!

Being a lot larger than the dwarf hamsters – about twice the size – they have quite a bit of energy to burn and require exercising.

These hamsters love to run around the garden or house in a hamster ball and if you build them an expansive hamster run they will love you forever!

Chinese hamster

Length 3-5 inches (including tail)
Weight 1-2 ounces
Lifespan 2-3 years
Temperament Intelligent, a little shy, need taming

Most hamsters have short, stubby tails to match their stubby legs, but the tail of a Chinese hamsters is actually relatively long.

They are more similar in appearance to mice than the other domestic hamster breeds with that longer tail and long, slender body.

There are two coloration types:

1.Agouti coat with black line along the spine and ivory belly


2. White coat with spots of colour


Are they a dwarf hamster?

Some things you read will say they are, but they are not true dwarfs and it would be better to simply describe them as a mid-sized hamster.

They can be shy to begin with and take a little time to warm to humans. But, if you can be patient and take the time to handle them a lot from a young age they will turn out to be friendly pets.

They are intelligent and do require a lot of stimulation and activities to keep them from getting bored.

While they can be part of a same-sex pair or group, like Syrian hamsters they are largely solitary creatures and can be aggressive towards one another, so it would be best to keep them alone.

Dwarf hamsters

Hamster care is obviously very important for all breeds, but pet owners should be especially careful with the three dwarf hamster breeds.

Being very small animals, dwarf hamsters can be great escape artists so it is best not to keep them in a traditional hamster cage with wires.

Instead, we recommend housing them in an tank (plastic or glass) with a mesh lid.

Also, make sure that they have hamster wheels that are solid with no gaps. A hamster wheel with gaps could be tragically disastrous for these small rodents.

It doesn’t bare thinking about!

Winter white dwarf hamster (aka Russian hamsters)

Length 2-4 inches
Weight 1-2 ounces
Lifespan 1-2 years
Temperament Mellow, affectionate, sociable

Very small and quick, they are not ideal first pets for young children.

However, they are social animals and prefer to be in same-sex groups so children could enjoy watching them play together in their tank.


The three most common colours are:

  • sapphire
  • pearl
  • black and gray

They usually have a dark stripe from head to tail.

So not white? But their name is winter white!!

Their name comes from their fascinating ability to change fur color when winter approaches.

Pet owners can watch with intrigue as their pet hamsters get lighter and lighter in color – in the wild they can get to almost white.

They are both docile and very active. This means they make a nice pet as are happy to be handled, but can be rather noisy at night as they spend hours and hours running on their wheels.

Best not to keep them in your bedroom if you want a good night’s sleep.

Campbell’s dwarf hamster


Length 3-4 inches
Weight 1-2 ounces
Lifespan 1-2 years
Temperament Nervous, timid


Quite similar to the above breed, the main differences being that Campbell’s has a shorter, darker stripe on it’s back, less hair on the feet, and smaller ears.

These delicate animals are more nervous and reserved than other hamsters, so would appreciate some additions to their tank where they can hide and feel safe.

Due to their timid disposition, they would prefer a calm and patient owner to a household with young children – they are known to bite when scared.

Roborovski hamster


Length 2 inches
Weight 0.5-1.5 ounces
Lifespan 3-4 years
Temperament Energetic, sweet-natured, agile

Another dwarf hamster, this tiny creature is a very small animal indeed and is, in fact, smaller than all the other species of hamsters.

Though they have great temperaments and can be handled, they are very quick and nimble so don’t make great cuddlers.

Many owners prefer to take joy in just observing them in their tanks.

They enjoy companionship and will be even more active with a friend around, so if you give them a large enough living space with plenty of toys they will keep you entertained for hours 🙂

Just make sure you have a same-sex group unless you want loads of cute hamster babies to look after.

In the wild, they live in the desert and spend hours and hours running along sand dunes.

This natural energy has not been lost in domesticated breeds.
