Can Hamsters Live Together in the Same Cage?
Yes, some can, but it will vary depending on the breed of the hamster, their personality, and how much space they have.
As for the breed, each breed has its temperament. Each hamster is different; some prefer being around others, while others prefer being alone. But certain hamster breeds are more inclined to live together than others.
With personality, hamsters are just like humans. Each has their personality and likes things differently.
Some hamsters like to be the dominant ones and bully other hamsters around. Others are shy and want to be alone. Then, others are wild and playful and enjoy having a playmate in the cage.
The living space is another factor in determining if the hamsters can live together. Too small of a space will cause the hamsters to get stressed.
They might fight each other over food bowls, sleeping space, or just out of being stressed.

6 Tips To Keep Hamsters Together
Here are some ideas you can do at your house to help your hamsters live peacefully together.
1. Large-sized Housing
If there is more than one hamster in the cage, sooner or later, they will start to get stressed.
This is because of the limited space in the cage. Since they don’t have a lot of room to move around, they may fight each other.
It’s essential to get a cage that has plenty of space for all the hamsters to move around so your hamsters can live together in the same cage.
2. Keep Hamsters of the Same Sex Together
If you’re not planning to breed the hamsters, it’s a good idea to keep them together with the same sex.
Whether you have a pair or five hamsters, keeping the same sex together is best to avoid an unwanted pregnancy.
Hamsters are one of those animals that reproduce very quickly. If allowed, hamsters can breed every month! At each birth, you can expect between 5 to 12 hamster babies.
Unless you’re planning to sell the babies or have an additional cage to keep their offspring, it’s best to keep the same-sex hamsters in the same cage.
3. Provide Multiple Feeding Locations
Hamsters are animals that seem to fight over everything when kept in a group. So, when it comes to food, you should always have multiple food and water bowls for them.
There should be at least 1 bowl for every two hamsters. This way, they will have an option to pick the bowl they want to eat from.
Also, if there is a more dominant hamster in the group, the less dominant ones can go elsewhere to eat.
When placing the food or water bowls, keep them far from each other. This way, while feeding, they won’t get cramped with each other.
4. Introduce Them When They Are Young
Hamsters that are introduced at a young age to each other tend to live well together throughout their lives.
So, if you’re planning to keep multiple hamsters together as adults, introduce them to each other when they are no older than 7 weeks.
During this time, they will stay close to each other for comfort and protection. After 7 weeks or so, they will start wandering off from the group.
If you introduce them when they are a bit older, they may fight each other for the first couple of weeks.
Hamsters are playful animals, and their playing might turn serious, especially when they don’t know each other well. Always be on alert for any fighting between them.
5. Keep Them Busy
Hamsters that are kept together will probably start fighting each other when they are bored. Hamsters are curious and playful animals.
So, to prevent them from fighting one another, keep a lot of toys or build mazes to keep them busy.
As long as they have something to play with or activities that keep them active, they’ll be less likely to fight each other.
6. Observe Their Behavior
Hamsters can live happily together for many years if they are grouped correctly. But they can turn on each other for no apparent reason, and it can become deadly, too.
This means you must always be on the lookout for any strange behavior. Some behaviors to look for are below.
- They are always hiding.
- They fight often.
- They are losing weight.
- There are scars on them.
- They have a loss of appetite.
By observing their behavior, you can keep them safe from each other and reduce their stress level. If a hamster seems to cause too much trouble, it’s best to remove them and put them in a separate cage.
How To Introduce Two Hamsters to the Same Cage?
If you have adult hamsters you want to live with, you’ll need to introduce them slowly first.
Simply putting both in the same cage will cause stress in both of the hamsters. Sooner or later, they may start fighting each other for everything that’s in the cage.
To introduce two hamsters to the same cage, you’ll need 1 small cage and 1 large cage.
Here are some steps to introduce them to the same cage.
- Place one hamster in the small cage. Then, gently place the small cage into the larger one. The other hamster should be in the large hamster cage.
- Allow the two hamsters to become accustomed to each other. Swap them daily so they don’t get too possessive of the territory. Do this for about a week.
- After a week, place both hamsters in the same cage and observe their behaviors.
If they get aggressive at each other, repeat the process. After some time, once they feel safe and not threatened, they will start to become friendlier with each other.
How many hamsters can live in a cage together?
A maximum of 2 hamsters can live in a cage together to avoid fights.
Can guinea pigs and hamsters live together?
No, you should never put a hamster and guinea pig together. Most breeds of hamsters are territorial and solitary animals. Because of their instinct, they will defend their burrow and food against the guinea pigs.
Can hamsters live together in the same cage? This question is very relative and difficult to answer since it really depends on many factors.
If you want your hamsters to live together and they are not from an aggressive breed, like Syrian hamsters, put them together when they’re no older than 7 weeks. If they are adults, you can try a gradual transition.
But remember that some hamsters are too aggressive and simply won’t accept another one in their cage. So, always observe their behavior, so your pets can always be safe.
