Can Hamsters Live Together In The Same Cage? (Warning)

We all love a bit of social interaction, and it’s normal for us humans to crave it. However, not all rodents are the same. Perhaps you are interested in getting a second hamster? Let’s find out if hamsters can live a happy life with another hamster.

Hamsters are best kept away from each other in separate cages. Hamsters prefer to be solitary from the age of ten weeks. Introducing another hamster not from the same family into another hamster cage will stress both adult hamsters. In addition, hamsters often turn violent towards each other, which can be fatal.

Dwarf Hamsters are the only hamsters who could live together without violence with a sibling, but only if they have grown up together. You will need to make sure that the cage is much bigger, so they have enough space to reduce any territorial disagreements. However, don’t be surprised if they do have disagreements as the possibility is still high although not as high as other hamster types. You need to ask yourself is it worth the risk.

Best Practises For Getting Another Hamster

If you want another hamster, you will need separate cages for them both. Keep them out of each other’s way when out of their cages—dont risk introducing them to each other, as its a very high chance that they will fight. Fighting with each other will cause tremendous stress on your hamsters.

  • Keep them separate, it is that simple! Hamsters are very much known for their aggression towards other hamsters.

Why don’t hamsters like each other?

Use gloves such as garden gloves or any thick gloves that can protect you from their biting, however, you shouldn’t delay in separating them. Hamsters do not like to share their living space.

Conclusion

We now know that you should never mix hamsters. Hamsters prefer to live in solitary confinement. Hamsters are stress-free and happier on their own. If you want to get another hamster, you must treat them as separate pets in separate cages and not introduce them even when out of their cage. I think for us humans to get our heads around the fact that these cute balls of fluff don’t like the company is very much difficult. However, it’s just worth the stress on the hamsters.
