Reasons Why Guinea Pigs Fight

You must have an observation as to why do guinea pigs fight because it might be a problem that needs to be addressed immediately.

The following are some of the reasons for the rodents to fight:


#1. Guinea pigs start to have a dominant behavior

If you have many pet cavies at home, there should be one to practice its dominance

Of course, there will also be a challenger that will prove its strength, and due to that, a piggy fight will occur.

The cavy that will win the duel will then be the most dominant in the pact.

You have to understand that the fight is not an issue if only a cavy backs down.

But if that scenario won’t happen, things will then become more aggressive and threatening.

If you witness this moment, you have to intervene and stop the cavies from fighting each other. (please read here why does my Guinea pig bite me)


#2. When a guinea pig is in pain

Piggies are peaceful, and they get along with other guinea pigs if you pair them well.

There will be instances in which a cavy will start to act up, and the very first thing that you must do is to check if your beloved pet is in pain.

Like us, humans, a cavy who is not feeling well will tend to get annoyed and cranky.

To make sure that your pet will be free from pain, you should feed it with healthy foods like fruits and vegetables for robust growth.


#3. The cavy has a small cage

If you own more than one guinea pig and you are continuously adding more, the cage that you allocated for them will be too small for their number. (please read here how much space do Guinea pig need)

Due to the little space for them to roam and play around, these rodents will get annoyed at each other and will start to fight one another.

#4. Boredom

If you do not give enough toys or food to your beloved guinea pigs, I am sure that they will soon start fighting because of uneasiness and boredom. (please read here how to entertain Guinea pig)

Let me tell you a short story.

I have a newly bought cavy, and her name is Ginger. I placed her in the case alongside my older guinea pigs.

There was an instance when I became busy at work, and I was not able to give toys to them.

That time was when my cavies started to fight each other, and in the beginning, I was not sure why.

It came to my senses later on that maybe they are fighting because they are bored.

I tried to give them more toys and delicious foods, and I have noticed that they became calmer and did not fight each other often.


Things You Should Do When Guinea Pigs Are Fighting

The first thing that you must do is to identify the situation whether the piggies are fighting due to dominance reasons.

If yes, it is essential that you automatically separate the two into different cages. Ensure that your pets are not injured in the fight’s duration so that no further issues will occur.

After one night, try to put them again into one cage and see if they will continue the duel.

Things You Should Do When Guinea Pigs Are Fighting

There is a 50 percent chance that they will be friends, and there is also another 50 percent in which they will again start to fight.

If the latter part happens, separate them, and the more aggressive guinea pig needs to be checked up by the local veterinarian.

Why is that so?

It is because maybe there is a hidden issue behind its behavior as to why it starts the fight.

If the pet has addressed the problem, then it is time for you to join the cavies again with each other.


How To Prevent Fights Between Guinea Pigs

You must understand that prevention will always be better than cure.

The best thing that you can do is make an environment or put them in an environment that will prohibit guinea pigs from fighting.

During the fight, there is a high chance of injury, which can also endanger your pet’s life. (please read here why is my Guinea pig shaking)


Step #1. Get a giant cage to accommodate more guinea pigs

If you want to have many guinea pigs in one place, you have to consider that these adorable rodents would be pleased to run around and play hide and seek.

For them to do that, they need enough space for the running sessions.


Step #2. Give them lots of toys

Since cavies are curious and get bored quickly, you have to offer them different stuff to entertain them.

What are these things? And the answer is toys of course!

I am sure that your piggies will love the variation of toys that you let them play with every day, and by that, they will be occupied and avoid boredom.



The most important thing that you have to understand is the reason why do guinea pigs fight.

After that, if you found out that they are in a small cage, it is time for you to step in and separate the cavies to avoid injuries.

An efficient pet owner will always want the best for the guinea pigs, so you need to observe their behavior.

I hope that you have learned lots of stuff in this blog post.
