Can hamsters get depressed? Yes, but a depressed hamster doesn’t show depression or sadness in the same way it shows anger and boredom. But the most common cause of their depression is not meeting their needs like a safe environment and the right food. You’ll notice a depressed one if they refuse to eat, skulk and curl at the corners of the cage, or barely move.

However, a lack of happiness doesn’t always equate to depression. An unhappy hamster will not be scared to show you that they are unsatisfied. But what are the signs that your hamster is not happy? This article will answer the question of how to tell if your hamster is happy.

In this article, I will answer the question “is my hamster unhappy?” or “how to know if your hamster is happy?”.


How Much Does Owning a Hamster Cost

I know many owners ask the same question, like how to tell if your hamster is happy or how do i know if my hamster is happy? Common problems owners have is that it’s hard to know if their hamster is happy or feels content with his living arrangements. If only they can provide you with feedback or show how much they appreciate your little efforts, life will so much be more comfortable for you and them. 

Aggressively Attacking and Biting You/Cage Aggression

Cage aggression is a huge sign of an unhappy hamster. Try putting your hand in their cage, and if you think they will bite or just be aggressive with you, this is not a good sign of a healthy or happy hamster. Unsatisfied hamsters are more reactive than usual and will bite whoever or whatever approaches them.

When you approach and see your hamster showing its teeth, moving its ears backwards and forward, or emitting grunts, it’s preparing for an attack, you might want to pull your hands first. When this happens, do what’s usual. Let your hamster remain calm for a couple of minutes and come back when they are feeling a bit better, perhaps with a treat.

Chewing the Cage

Hamsters are very quiet household pets, but having them chewing on cage bars can be incredibly annoying. Aside from cage biting is a telltale sign that something is wrong; it’s terrible for their teeth and nose, especially for the young ones. The metal is most likely covered in toxic paint while the small spaces between bars are too narrow for their nose causing bald spots. 

More like nail-biting in humans, bar-biting means they feel uneasy or anxious. They could be stressed or feeling really depressed. These are signs that your hamster is not happy or maybe you are facing an upset hamster. To prevent them from doing this, read our article, on how to stop your hamster from bar biting.

However, stopping your hamster from doing doesn’t solve the problem. It’s important to ask yourself, what else can I do to make my hamster’s living situation better? 

this bar biting is very dangerous


Hamsters love to stay busy around the cage, but if they sleep too much and ignore their food and even treats can’t cheer them up, it’s a red flag that they are not happy or probably sick especially if they are not older than 2.5 years old. Hamsters that don’t have the appetite or motivation to eat can lead to dehydration, which can be very bad for their health. 

If you notice that your hamster doesn’t play around as usual like burrowing, chewing, digging, hoarding, and more, this is alarming.

Always on their Sandbox

Like cats, hamsters enjoy grooming or cleaning their fur, but if you notice your hamster spending more time than usual in their sandbox, it might be a sign that they have mites or skin problems.

Hair loss is also common but takes note that it can be seasonal or happen for older hamsters. Flakiness, redness, lesions on the skin, or scratching more than usual is not very good; these are signs that your hamster is sick, we advise you to see a vet soon.

They Always try to Escape

Hamsters are escape artists from time to time, but if you notice this happening every day, it’s a big sign that your hamster is feeling unsatisfied or bored. The cage is most likely too small, or they feel really bored because of the lack of toys or are most likely not getting enough time in the playpen. Female Syrians are the best escape artists if you have this breed, it’s recommended that you get an even bigger cage. 

A hostile environment is a common stressor for the hamster. When hamsters feel aggressed, they likely prepare their way out. They will look really angry with their forward-facing ears and puffy cheeks. If something is bothering or scaring them away, they will try to escape.

Just like we humans, hamsters can experience happiness, optimism, sadness, and depression. If you notice your hamster shift in mood, from a gloomy demeanour to a rosier approach daily, remember that this is normal.

Here are signs to help you tell if your hamster is happy:

Happy to take Treats from your hand without attacking You

Hamsters have poor eyesight, you need to rely on their sense of smell and hearing to gain their trust. A happy hamster recognizes your voice and scent and tends to get excited when your approach. When a hamster takes the treats on your hand without attacking you, then it’s a good sign that they are very comfortable with you and the surroundings. 

Try placing a treat in your hand and slowly in the cage. Make sure you wash your hands first to remove possible food smells from your last meal. With your hand in the cell, stay put, and let your hamster come to you, don’t wiggle your fingers, and don’t chase them around. If your hamster is ready, it will engage; otherwise, if not, leave it be for the time being. Those are the signs a hamster is happy.

Excited when you come near the cage or time for playout of the cage

A happy hamster loves to run around, play well, stretch and yawn, and groom themselves while out with you. When they hear you approaching or coming near the cage, they will get excited and go and welcome you while waiting for you in the door cage. 

Hamsters are solitary by nature, but they do enjoy human company. Yes, it may take time for a hamster to get comfortable and bond with you, but once they get used to stroking your hamster’s fur, they will need all the attention they can get.

  1. If hamsters are nocturnal, I would be asleep when this little guy is active. He sleeps all day.

    • To be more specific, hamsters are crepuscular – which means they are most active during the twilight time or more likely awake and active during dusk or dawn. However, it is not unheard that hamsters do adapt in a specific sleeping pattern (like any mammal), be it at night or during the day and most likely stick in that pattern. This is not so common but definitely not unusual. Many female hamsters especially in the wild are diurnal – which means active during the day.
