One of the biggest concerns of hamster owners is probably hamster aggression. Hamster aggression is when a hamster acts hostile and does things like biting and attacking you. We all heard the story from a friend or even personal experience that a hamster bit a finger and drew blood.

In many cases, this is the reason why a lot of people give up their pet hamsters. Because, basically there are hamsters that don’t bite. In this article, we will discuss why hamsters are trying to bite you, how to spot warning signs, and of course, how to get hamsters to stop biting.

One thing you should remember is that your hamster doesn’t hate you. When a hamster bites or attacks, there’s always a reason, mostly due to their instinct. Below, I will help you understand your hamster more, why this biting behaviour occurs, and how to stop, minimise, or handle it.

Naturally aggressive

Hamsters are naturally aggressive. Because of their size, hamsters in the wild were seen as prey animals. Due to this, hamsters have to develop a quick defence mechanism to survive. Hamsters have a fight knee-jerk reaction in a fight or flight situation.

Domesticated hamsters still have this instinct. When an unknown presence is sensed, hamsters will quickly put their guards up and be ready to defend or attack as a defence. Regardless if you are a human, a predator animal, or even if you are a hamster or a hamster from the same family.

This is the same reason you cannot house more than one hamster in a single cage even if they are related. Eventually, the defensive and aggressive instinct will kick in which will result in fatal fights.

You are seen as a danger or predator

A hamster will bite or attack you if you possess any danger or are seen as a danger. If you wake up a hamster or spooked them, it could also be the reason for your hamster to bite you. Anyone, including another hamster or even a person they trust, a hamster will always consider you as a danger to themselves in many situations – it’s just a reflex.

Unhappy or stressed

When your hamster is stressed, feeling anxious, feeling unwell, bored, or unhappy, it can be short-tempered and act aggressively towards you. One of the signs is you will find your hamster biting bars. Unhappiness, anxiety, stress, or boredom often results in an unsatisfying cage size or number or enrichment inside the cage.

You tried to handle or hold them

Hamsters love being alone, sure, there are friendly hamsters who sometimes like your attention. In general, hamsters like being in their own element, playing, burrowing, or chewing on chew toys. When a hamster doesn’t feel like being held but you try to hold them, they would tell you to stop by biting you.

Your hand smells like food

If you recently touched food and didn’t wash your hands before handling your hamster, they might think that fingers are some sort of food.


Hamsters move very quickly, especially the Dwarf Roborovski. Often it’s hard to spot the signs that your hamster will bite you. But the Syrian hamster, the biggest domesticated one, is usually tamed but still can be aggressive. The good thing is, it’s easier to tell when it’s about to bite you since Syrian hamsters are not as quick as Dwarves.

Here are some hamster bite warning signs:

  • The hamster is looking at you or your hand, whichever part of your body is near to them
  • They pause for a good second, staring at you (or your hand)
  • Running or charging towards you
  • Running around the cage tirelessly
  • Biting the bar cage – is usually a sign that they are unhappy (tips on stopping your hamster from bar biting)

Unfortunately, unlike dogs or cats, hamsters don’t really growl or hiss to let you know that you are annoying.


Why Is My Hamster Always Sleeping

There are many things you can do to stop your hamster from biting you. Like taming, introducing your scent, gaining their trust, and knowing when not to approach or handle your hamster.

Taming a hamster

The first thing you need to do is tame your hamster. This process starts from the moment you bring them home. It’s vital that you leave your hamster alone in the cage for the first week. This allows them to get settled, get familiar with the cage, and spread their scent all over.

After a week, you may now start taming your hamster. During the taming process, the goals are:

  • introducing your scent to your hamster
  • getting comfortable with your hamster
  • building trust between the two of you

Make sure to not wear too much perfume or not use scented hand soap before handling your hamster. It’s important to simply have your natural scent and let your hamster know who you are by getting familiar with it.

Next, getting comfortable with your hamster means not being scared of them. I was not scared of my hamster in the beginning until the first biting incident we had. How about gloves for handling hamsters? When taming or holding your hamster, you must wear thick gloves so you don’t have to worry about getting bitten painfully. Getting bitten can really traumatise you and develop fear towards your pet hamster.

Building trust between your hamster and you is the most challenging part. Because after your hamster learn who you are, they can still be hostile to you in some situation. To gain your hamster’s trust is to let them know you won’t hurt or stress them. You can do this by giving them their favourite treat whenever you try to hold or approach their cage.

Observe your hamster’s behaviour

Observing your hamster’s behaviour and personality means you will learn what your hamster like and dislike. For example, some Syrian hamsters like getting cuddled or held while Roborovski hamsters prefer to be left alone.

If you know that your hamster doesn’t like too much noise, your perfume, or bright lights near their cage, you will know what their buttons are and how not to push them. By doing this, you will learn how to provide a comfortable environment for your hamster.

Provide suitable home

One of the best solutions how to get hamsters to stop biting is making sure they have a suitable cage. This means their enclosure is spacious and meets the right floor size. Having the right cage brings so much comfort and joy to your hamster.

This also means the bedding is safe, there are plenty of toys, and they have everything a hamster needs. From toys, food, water, sand, and more.

Don’t forcefully pick up your hamster

Do you remember how to pick up a hamster for the first time? Instead of forcing your pet to interact with you, once you already spent time taming them, you should put your hand out and let your hamster crawl on top. This is an easy way to tell if your hamster is ready to spend time with you or not.

Never ever wake them up

Take this one religiously. Hamsters sleep during the day and wake up at night. During the sleeping time, never wake up your hamster. If you disturb a hamster from their sleep, it causes irritation and a foul mood which leads to biting when you try to hold them. This will only strain your relationship and cause stress to your pet.

Of course, there are exemptions, like cleaning the cage or replenishing food or water before you have to leave the house and will be gone for long hours. If you do really have to wake your hamster up, don’t hold or touch them for a few hours and leave some treats for them later to cheer them up.

Do not spook your hamster

Spooking your hamster will never end well. Unlike dogs who have lots of sense of humour, hamsters are like cats who won’t bat an eye before hitting you. Sneaking or scaring your hamster will just show how you can’t be trusted or pose a threat.

Let your hamster out for 10-minutes a day

Make sure to let your hamster out of the cage for 10-minutes a day. This will allow your hamster to be in a different environment filled with areas or toys to explore. It lets your hamster burn some extra energy, let out some frustration (especially when feeling bored in the cage), and overall improve their mood.

To safely do this, you can use a hamster playpen, add running wheels, climbing platforms, mazes, and tunnels.

Treats are the key

Last but not the least, give your pet plenty of healthy hamster treats. You know this is one of many ways on how to bond with your hamster. These can be healthy treats like lean chicken or boiled egg. Any food that is not part of their food bowl inside the cage is a good treat. Everyone feels better after eating delicious food, right? This is also a good way to build a great relationship with your hamster.


Hamsters may be aggressive and sometimes scary pets, but deep inside, they just want to be understood and need someone who has the patience to get to know them. It may be challenging to build a relationship with your hamster but it’s all worth it. Once you gain your hamster’s trust, you will create so many memories together.

  1. i just got my hamster it’s a sryian female hamster, i’ve had her for about two days and i feel like she is scared of me because every time i try touch her she flinches and i want her to get to know me ,, any tips?

    • Our female Syrian does the exact same thing as well as biting aggressively. We’ve had her for 3 weeks now I’ve spent a lot of time trying to ‘tame’ her but every time I think we’re making progress she bites me, draws blood, and then I don’t feel like going near her. She’s very skittish around us and her mood is constantly changing. One minute she’ll be next to my hand and gently sniffing it then the next minute she’s biting it. It’s quite frustrating to be honest. I have had her out of her cage and she has over to my face sniffed around and been fine but at this point I’m not sure what more I can do than wait.

      • If it’s only been 3 weeks, it’s not much time. This means that if you follow the advice to leave her in the cage for the first week, you’re only taming her for the last 2 weeks. Try not to attempt to hold her every day because she might still be getting used to her cage and your scent. When she doesn’t bite you, give her treats, and when she does, don’t give her rewards. But please always wear gloves. In this way, if she bites you, you won’t feel defeated. Instead, you can put her back to cage for the day. Syrian hamsters can be the hardest to tame and really requires lots of time and patience. You can instead make a schedule for it. So if you try to hold or tame her the same day every day, this could help her settle and have some sort of routine. She’s still a baby and have lots of energy and could still be adjusting to being away from her litter. I hope she comes around xx
