So, can hamsters and guinea pigs live together? No, guinea pigs and hamsters can’t live together. Although both animals are rodents, they have major differences in their personality and lifestyle. As a result, keeping them together will create an imbalance for both of them and with their habits, they’ll naturally annoy each other. 

We aren’t just putting in a random statement. To justify our statement, we have much more to elaborate on. The facts will include cage requirements, personalities, and playtime of these furry little creatures. Keep scrolling down! 

Reasons Why Hamsters & Guinea Pigs Can’t Live Together 

As mentioned earlier, guinea pigs and hamsters are polar opposites when it comes to living together. Many would think guinea pigs are harmful to little hamsters, but they are not. 

Reasons Why Hamsters & Guinea Pigs Can't Live Together

We would rather break down the factors that refer to not keeping these animals together before you blame the guinea pigs. Let’s read the reasons below.

Living Territory

Surprisingly enough, guinea pigs are immensely friendly social animals.  On the contrary, despite being small, hamsters are very aggressive when it comes to sharing their territory. Actually, they love to live alone. 


Sleeping Schedule

Hamsters don’t sleep at night since they’re nocturnal animals. So, when guinea pigs sleep at night, the hamsters would keep them awake if left together. The same goes for the guinea pigs as they would keep the hamsters up during their day sleep time.


The only thing these two have in common is their obsession with exercise. Although both of them love to play, their playing methods are different. 

Guinea Pig

Your guinea pig might not use the hamster’s playing tools, it will use the entire cage, and the hamster won’t like it. Guinea pigs hate to sit in one place, while hamsters are so into this. Consequently, while jumping, guinea pigs might bump into your hamster.

This’ll make the hamster even more aggressive. He might jump on the pig, scratch it and create a life-death situation. 

Why Is It Hard for Guinea Pigs to Live With Hamsters? 

People who know guinea pigs get shocked knowing they can’t live with hamsters since they’re very social animals. But hamsters are extremely sectional and, of course, solitary. 

Some hamster breeds can manage to live together, but they often fight each other until one releases the last breath. This is primarily why experts suggest not keeping guinea pigs with hamsters. 

Why Is It Hard for Guinea Pigs to Live With Hamsters

Since hamsters are territorial, they want everything separate, space, food, playtime, or sleepytime. And they mark all of these using their scent glands. 

So, it was never about the guinea pigs. Hamsters can’t possibly live with any other animal. They’ll end up torturing the other animal in a way or two. 

Note: some might argue that hamsters in the breed Dwarf live together well. Actually, they can live together as they have been kept together since they were babies. They recognize each other’s smell while growing up in the same size and species.
