When you visit a pet store to buy a hamster, you probably notice that there is an enclosure full of these tiny rodents. Even though they are all crammed into a small area and trampled by one another, no one is hurt. This could lead you to believe that housing hamsters together is completely safe. After all, it must be safe if the pet store does it.

Unfortunately, with hamsters, that way of thinking doesn’t lead to too much. In actuality, hamsters are lonely animals. While a few uncommon varieties of hamsters can coexist, keeping several together will usually end badly. When forced to dwell in close quarters with other hamsters, they may even exhibit extreme violence.

Certain dwarf hamsters are indeed happy being maintained in pairs, and with a little luck, you might even be able to maintain a horde of hamsters. However, you’ll be setting yourself and your hamsters up for failure if you try this with the incorrect animals.

Are Hamsters Safe to Keep Together?

The common response is no. Hamsters shouldn’t be kept in close quarters. Most hamsters in the wild live alone and only look for other hamsters to breed with. The lives of hamsters kept in captivity should be as similar to those of wild hamsters as is practical. Depending on the species of hamsters you’re working with, the repercussions of breaking this guideline could be dire. When hamsters fight, it can lead to harm, disease, tension, anxiety, and in severe circumstances, even death.

We’re going to take a deeper look at a few common kinds of hamsters kept as pets and talk about the chances of them coexisting happily so that you don’t put two of the wrong hamsters together.

Can Syrian Hamsters Coexist?

Of all the hamsters that are frequently kept as pets, Syrian hamsters are among the biggest and friendliest. When fully grown, they are about 5-7 inches long and up to 6 ounces in weight. Although these hamsters are regarded as being quite sociable with people, they are not sociable with other hamsters. These hamsters only come together to breed, and you’ll never see two of them sharing a burrow in the wild. They are fiercely possessive, so if you put two Syrian hamsters together, fighting is practically a given. Syrian hamsters should never be kept together.

Can two robo hamsters coexist?

One of the rare hamster species that have been seen in the wild cohabiting in couples is the Roborovski hamster, sometimes known as Robos. Even in the wild, they are typically found alone, thus this is the exception rather than the rule. Robo hamsters are among the species most likely to get along in a shared environment, despite this. Robo hamsters are an excellent option if you want to keep more than one hamster in a single enclosure. Just be sure to leave plenty of room to avoid fights.

Do Winter White Hamsters Get Along?

Unfortunately, you won’t likely locate any pure snow white hamsters without doing some major searching. Nevertheless, winter white hybrids are rather widespread, and these hamsters occasionally coexist in packs in the wild. There have also been instances of winter white hamsters sharing burrows with other animals, and they can even be seen in groups considerably larger than just two hamsters! Although it can be challenging to offer adequate space for two hamsters in a small enclosure, two or more winter white hamsters should be able to live together without too many problems.

Do Dwarf Hamsters Get Along?

Dwarf hamsters come in a variety of varieties, such as winter whites and Campbell’s Russian dwarf hamsters. Many dwarf hamster species may coexist successfully even though the majority of full-size hamster species cannot be maintained together for their safety. This includes the hybridized Campbell’s Russian dwarf hamster with winter whites, which is common. These hamsters can be raised in couples or even small groups, just like other hamsters.

However, this does not imply that all dwarf hamsters make good housemates. Chinese hamsters are also dwarfs, however, unlike winter whites and Campbell’s Russian dwarf hamsters, they live alone. Even if you keep just one male and one female together, Chinese hamsters will fight if kept together. They should only be kept together for mating purposes and kept in separate enclosures.

Observe These Guidelines for a Successful Hamster Cohabitation

Even if you choose a hamster species that are tolerant of other animals living in the same enclosure, you will still need to take extra precautions to set them up safely. You can’t just put two hamsters in a little cage and hope for the best. Instead, you should adhere to these instructions to make sure your hamsters have all they require to live in harmony without fighting.

1. Begin them Together Young

Two adult hamsters introduced to one another nearly invariably fight. It is advisable to introduce two newborn hamsters together in a shared enclosure because they can become territorial. As they get older, they’ll learn to get along and avoid many of the territorial and dominant tendencies that you’d observe when introducing two adults.

2. Same-Sex Relations

You must maintain a male and female together for mating. However, after giving birth, females might develop excessive territoriality and aggression. Even worse, they might consume their own young! Adults in the same enclosure who experience this risk are also at risk. However, you are much less likely to see fighting between two hamsters of the same sex kept together, whether they are two males or two females.

3. Pairings of the same species

Two dwarf species may be similar enough to coexist despite their differences in size, but this is rarely a wise decision. Despite having comparable sizes, temperaments can vary tremendously. Even while some dwarf species support cohabitation, not all of them do. Whenever possible, only house hamsters of the same species together.

4. Create backup containers

Even if everything appears to be going well, anything might happen. Your hamsters may get along well one day and then start fighting the next. You should be prepared with a backup enclosure where you can shift one of the hamsters to keep them both safe if this occurs.

5. Offer Plenty of Resources and Space

Even if your hamsters normally get along peacefully, conflict may break out if supplies are limited. Two hamsters require a lot more area than one does, so you’ll need to make sure the enclosure has plenty of room. Make sure there is sufficient food and water so that there is no need for conflict over scarce resources.


Do not be deceived by the hamster enclosure at the pet store. It’s not a good idea for you to keep all of those hamsters in the same cage just because they do. The majority of hamsters are solitary animals that, when exposed to other hamsters, become hostile, violent, and territorial. Nevertheless, a few kinds of hamsters can be kept together safely if you take some common sense precautions, such as providing enough room and supplies and only housing hamsters of the same sex and species.
