Hamsters come in so many furs and colors and patterns it’s hard to remember which is which sometimes. And other times, they turn around and surprise you and change their fur ! Nothing as dramatic as going from blonde to redhead, but sometimes some hamsters might change their color.

Do hamsters change color ?
Some hamsters can change color, either because they are very young and coming into their adult fur, or because they are getting very old and turning a bit gray, or because they’re a type of hamster that turns white when the cold season hits. Aside from the Winter White hamsters, no color change is dramatic but it’s a fun thing to observe in your hamster.
Hamsters come in so many fur colors, to begin with, it’s interesting to see how their fur can change as they age or the seasons change. Let’s start with the most common reason their fur can change.
Very young hamsters will change their fur as they become adults
When hamsters are born, they are hairless. Then they get their initial fur growth, and it’s usually something very light, very fluffy, and very close to what their adult color will be. But as they reach maturity (about 3 months) their fur color will develop more. Some colors will be brighter, and some extra hairs will grow in, especially agouti hairs (with black at the end of each hair).
For example when I first got my Teddy, he was maybe a little over a month old. So tiny ! He was a golden Syrian hamster, so he already had a light orange/gold on his back, with grey ears, and white markings on his face and feet. But as he grew a little more, I noticed he had a bit of a spot on his forehead, like a gray smudge. At first, I thought he got dirty somewhere, somehow.
But nope, turns out he actually had some agouti hairs growing all over him, and a very pale grey mark on his forehead. So as an adult my teddy was orange, with agouti hairs, mostly on his back, and a grey mark on his forehead. He was might lighter looking as a tiny little 1 month old boy.
Some hamsters change their fur in winter
Some hamsters can change their fur when winter comes. This change is triggered by a shift in temperatures, but especially by a shift in daylight. The only hamsters to do this are the Winter White dwarf hamster, otherwise known as Siberian dwarf, or Djungarian dwarf.
In the wild this happens all the time. But when we’re talking about pet Winer Whites, this rarely happens, because of artificial lighting, and the even temperature inside our homes. You can induce this change, but it means only subjecting your hamster to natural daylight and nothing more. I imagine this is easier to do in the countryside due to much less light pollution.
Very old hamsters lose fur and go a bit gray
Another reason for hamsters to change their fur is when they get very, very old. Like humans, old hamsters get slower, and turn gray, and start to lose their fur. Well not exactly the same, but they get silver spots. The most common places for silver or white fur in an old hamster are around the ears and neck, as far as I’ve seen. These changes seem to be more noticeable in Syrian hamsters than dwarfs.
Most hamsters have a short lifespan, around 2-3 years. The hamsters I’ve had, 2 died of old age and one is still around but also growing old. When Teddy died, he was almost 2 years old. His fur was thinning on his neck and back, and his ears were drooping a little, and he suddenly had these white tufts around his ears. He started looking alike a grumpy old man, balding but with a lot of hair around his ears.
When Eggwhite died, he was also almost 2 years old, but he was a creamy white so I couldn’t notice a change in color. But I did notice his fur getting thinner, his eyelids drooping a little, and he also developed some tufts around his ears like Teddy did before he passed away.
Both Teddy and Eggwhite were Syrian hamsters. My third hamster is a Winter White, called Rocket, but she’s never changed her fur in the 2 years we’ve had her. She can (theoretically) live up to 4 years, and so far we haven’t seen any signs of old age on her, such as white hairs, droopy ears or eyes, or even getting slower. The fur on her paws is a little thinner, but that’s the only thing.
Other hamster fur facts
Here are some other interesting hamster fur facts, since these little guys are far more fun than they appear. Their fur comes in many colors and patterns, but that’s not where it stops.
There are versions of Syrian hamsters with long fur
When scientists captured Syrian hamsters for their labs, they also bred them to be more docile and this also led to them expressing different fur patterns. In time the hamsters wound up with breeders, who tried to see if there could be long haired hamsters. And eventually they succeeded, long-haired Syrian hamsters are here and they look absolutely funny. The long hair can sometimes be long and flowy, other times it can be a mix of long and short with just a few tufts sticking out, and in some cases it’s long fur all over the hamster.
These long-haired hamsters sound fun, and they may seem a bit more cuddly than the others, but their temperament is the same. They don’t really enjoy being picked up, but you can try. Their fur requires a lot of extra care though, since it can easily get matted.
Hamsters are very clean creatures, and they clean themselves several times a day. But they weren’t ‘programmed’ for long fur, so they can’t clean it as well as short fur. Sometimes they need help, which brings us to the next point.
Long fur can get very matted
This is mostly the case for long-haired Syrian hamsters, but in theory it could happen to any hamster. When the fur becomes too long, the hamster has trouble keeping it clean and detangled. In these cases you can either help the hamster by brushing out the mats, or cutting the knots out. Both are quite difficult, and your hamster’s temperament will dictate how to handle this.
So let’s start with the first one, trying to brush out the matted fur. If you’ve ever had knots in your own hair you know how difficult they can be, and how painful it is to comb them out. You have to start at the ends, and very slowly work your way up. Your hamster will obviously not want to sit still for half an hour until you get all the knots.
This will be slow, and you will have to let the furball sit as he wants to keep him calm. Try to grab his attention with a small treat, and attempt to comb out some knots at his backside, starting from the edges. He might flinch, or he might not care; not all hamsters are the same. This won’t last long, and you may only have a couple of minutes to work on his fur.
That’s okay, let him be and try again in an hour or two. Don’t try to do this all in one day. It’s really not easy.
The second option, perhaps easier, is to simply cut off the knots you can’t brush out. Your hamster will get some uneven fur but this takes less time. Again, do this on the hammy’s own terms. If he wants to go away let him go away. If he squirms, put him down and try again later. Always use something to distract him.
You need a pair of very sharp hair cutting scissors. Hopefully the knots are towards the end of the fur. If there are any knots close to the body or directly against the skin leave them alone. The risk of hurting your hamster by accident is too high.
Like combing out knots, this can take a while too. Maybe your hamster doesn’t mind the sound of scissors, maybe he gets frightened. There is no safe way to keep him in place, without injury or extreme distress for both of you. Best to just go very slow, and use a good pair of scissors.
Hamster fur can grow back in most cases
Sometimes a hamster will lose some of its fur, and sometimes that fur can grow back. Not always, such as very old hamsters who lose their fur due to old age. Or hamsters with a genetic condition that prevents them from growing fur in the first place. The fur on these hamsters sadly won’t ever grow.
But if your hammy lost a patch of fur because of a skin condition, an irritation, ringworm, or just because he scratched himself too much, there is good news ! The fur can grow back, as soon as the skin condition is treated and healed ! In case of excessing scratching, it’s usually due to an irritant, like a rash, or the hammy got bit by something and it’s now itching. Once that is gone and the hamster doesn’t have a reason to keep scratching, the fur will grow back.
Hamster fur should never get wet, don’t bathe your hamster !
Hamsters have very delicate fur, especially the fluff right next to the skin. It’s meant to insulate the hamster and keep it both warm and cool, depending on the weather. Hammies are exceptionally good at keeping themselves clean, they lick and nibble at their fur constantly so it is always clean. Kind of like a cat cleans itself, except this one isn’t meowing.
There is no real reason to give a hamster a bath to clean it, unless it somehow got something on it that the hamster can’t or shouldn’t clean by itself, like car grease or ketchup.
If you do get your hamster’s fur wet, know that washing it with any sort of soap will disturb the natural oils on its skin. Not only that but these animals are so frail, they need to be dried immediately after getting wet since they can’t easily handle it. Where hamsters come from water (rain) is rare, so they haven’t adapted their fur to be water-proof.
So, it’s best to never put your hamster in a situation where it could get its fur wet. And never handle your hamster with dirty hands. The hammy will clean itself after you play with it even if you’ve just washed your hands, imagine how icky it’d feel if you picked it up with Cheetos dust on your fingers.
