4 Ways To Prevent Your Hamsters From Fighting

by Hamster Care

Thanks to COVID-19 we have all been stuck in the house together for months and months which has, inevitably, led to the kids bickering and fighting much more than usual. This forced imprisonment has made me appreciate why a hamster may prefer to live alone rather than seeking solace with a fluffy hammy mate.

There are some breeds of hamster, such as Dwarfs, that will tolerate sharing a cage with one another. But if you own two Syrian hamsters, then they should always be housed separately as these hamsters are territorial and therefore are known to fight.

The trouble is, how do you know when your hamsters are physically fighting and when they are just enjoying boisterous play? Hamster behavior is tricky to understand at the best of times, but the last thing you want to do is misread the signs and risk the chance of your hamsters getting hurt. Here we will explain all you need to know about hamsters fighting and ways to prevent your hamsters from fighting.

Reasons hamsters fight

If you do decide to get Syrian hamsters then they should always be kept in separate cages. These hamsters may be cute to handle but are fiercely territorial over their own space. So, from around six and eight weeks of age, Syrian hamsters need to be housed apart.

In additional to being possessive, the most common reasons why hamsters may fight is because they are limited on space, feel threatened or are stressed out by their cage mate. However, dwarf hamsters are a breed that will happily share their accommodation, providing they are with the same breed but different sex. But remember, they have not chosen their cage mate, you have, and therefore there is always the potential for a fall out.

You should be vigilant and watch out for any signs that your hamsters are fighting, to prevent your pets from getting hurt. You’ll know something is awry because when hamsters fight, they can be very noisy and aggressive.

Do male hamsters fight?

It’s very common for male hamsters to fight. This is a known issue, and some choose to avoid putting male pairs together.

However, it is possible for male hamsters to get along in the same habitat. They can get along for a long time and then have a falling out with each other, though.

You could have your male hamsters getting along well in the cage for months. Then something happens and the two just won’t stop fighting each other.

It’s a frustrating situation, but it’s something that you might have to deal with. There are ways that you can make it less likely that hamsters will fight that you’ll learn about later.

For now, you should know that males are the most likely to fight with each other. If you want to keep things as safe as possible, it might be better to avoid male pairs.

Do female hamsters fight?

It’s common for female hamsters to fight each other, too. However, there are some types of hamsters that are more likely to live peacefully together.

Female dwarf hamsters appear to be the most likely to share a living space without fighting. So if you want to try to keep hamsters together, it might be best to go with two female dwarf hamsters.

You still need to be careful to monitor the hamsters, though. If the hamsters show signs of aggression, you might need to put them in separate habitats.

Just be mindful of the situation to see if you can house the two female hamsters safely. If there are signs of trouble, it’s better to separate the two.

Do male and female hamsters fight each other?

Female and male hamsters can and will fight. Females can be a bit territorial and they will often give the males a bit of a beating if they choose to invade their territory.

In the wild, male and female hamsters usually only come into contact to mate. So living in the same space isn’t common.

There’s a good chance that a male and the female hamster will fight too much to be kept together. Many say that it’s better not to put your hamsters in this situation.

Hamsters can hurt each other when they fight. This isn’t something you want your pet to have to go through.

What to do if your hamsters fight?

Hamsters may look small but they can be fierce and a fight between two hamsters is not for the faint-hearted. Hamsters generally attack using their teeth which enables them to inflict serious injuries on their rivals, with some fights even ending in death.

Therefore it is important that if you see two hamsters fighting that you step in and separate them as quickly as possible.  However, breaking up a hamster fight is easier said than done – especially when they in throes of aggression as there is the chance that you yourself may be injured unintentionally.

Therefore, we recommend that you use gloves or try and place a physical barrier between each hamster so that once they have calmed down you can safely remove one. Once hamsters start to fight it is unlikely that they will be able to cohabit a cage again so they should be separated for good.

Ways to prevent your hamsters from fighting

If you do decide to house two hamsters together, there are a number of things that you can do to encourage harmony between your hamsters, although there are no guarantees that they will become best friends.

  • Separate breeds and sex

Female hamsters are known to prefer the company of others, whilst male hamsters will happily live on their own whilst mixing the sex of hamsters will only lead to the inevitable. You should never attempt to pair up Syrian hamsters regardless of sex, as these are solitary pets and need to live alone.

  • Introduce your hamsters slowly

Every hamster has its own personality and even with dwarf hamsters, there is a chance that they may clash. Therefore, you should never put two hamsters straight in the same environment. Introduce them slowly by placing their cages side by side so that they get a chance to smell one another and interact through the bars at a safe distance. After a number of days or weeks, if you notice them tolerating one another then you can place them in a brand new, scent-free cage. This will allow them the opportunity to get to know each other in a neutral environment, without one feeling more dominant than the other.

  • Size of cage

If you are going to keep more than one hamster in a cage, then it is really important that there is enough room for them to have their own personal space. If the cage is cramped, then there is more chance that your hamsters will fight. It is also a good idea to ensure that each hamster has its own house, bottle, food bowl and toys to prevent any fights over-sharing. Plus, just like children, hamsters can get bored, so either change the layout of the cage regularly or introduce different accessories so that they are stimulated and less likely to scrap.

  • Regularly clean out your hamsters’ cage

Although hamsters are relatively clean pets, when two or more are together in a cage they need to be cleaned out more regularly. Overpowering scents could start to stress out your hamsters so make sure they are spot cleaned daily.

Hamster squabbles vs. Hamster fights

It’s important to note that squabbles between hamsters are not uncommon, especially in the early days when they are asserting their positions within the cage.Normal fighting between hamsters is about dominance, and once one hamster puts the other one in their place it generally starts to calm down. Chasing, squeaking, sniffing, and squealing is considered normal behaviour, although it can look and sound upsetting at times.

As long as your hamsters do not come to any harm and they are happy to interact with one another on a daily basis in terms of sleeping, eating, and socializing, then just put the daily squabbles down to a bit of hamster rivalry.

Actual fighting looks very different! If you see your hamsters biting, clawing, chasing, or cornering another hamster to prevent escape then these are signs that there is bullying and fighting going on between your hamsters in their cage.

Are hamsters aggressive?

Yes, hamsters can be aggressive toward each other. They aren’t generally aggressive toward humans, though.

When you interact with the hamster it’s unlikely that it’ll bite you much. It might bite you if you scare it, but it isn’t going to act truly aggressively.

Hamster aggression toward humans is rare, but hamsters being aggressive toward each other is common. It’s easy for hamsters to get mad at each other and start fighting.

Since hamster aggression is such an issue, many recommend not keeping two hamsters in the same habitat. If you decide to try it, remember to be cautious and monitor the hamsters.

Can hamsters kill each other?

It’s more common for hamsters to kill each other than you may realize. Some hamsters’ fights might wind up being to the death.

This is why you need to take hamster fighting seriously. If you ignore the fighting, one of your hamsters could wind up dead in the cage.

There are even some types of hamsters that are known to cannibalize. Since hamsters are territorial animals, they might choose to kill and eat the other hamster in the cage.

You need to make sure that you choose hamsters that are as likely to get along as possible. Going with dwarf hamsters is the best recommendation.

You also want to ensure that the two hamsters have an ideal environment that will give them the best shot of getting along in the same habitat. Otherwise, it’s likely that the hamsters will come into conflict.


Hamsters are not like other pets in that they miss having company. Providing your hamster has plenty of human interaction then finding them a cage playmate is not required. If, however, you do want to get a couple of dwarf hamsters, please ensure that you integrate them slowly and watch out for signs of fighting. This way your hamster can make hammy friends without feeling threatened or stressed.
