Why Do Guinea Pigs Bite?

First, you need to understand that guinea pigs don’t bite like wild animals. You’ll hardly feel serious pain or deep bruises on your skin if a guinea pig bites but you may get hurt.

Now, this can be a bit confusing but you’ll understand later. Just continue reading.

As of now, no one knows why these little creatures bite. However, there has been proof of why they behave that way. Here are the possible reasons guinea pigs bite:

1. Fear

Understandably, a guinea pig will likely bite your fingers if it’s feeling scared. Naturally, animals put up a fight when they feel threatened.

Like the common saying goes like this, “attack is the best form of defense”. Whenever a guinea feels helpless, that is, unable to escape from a closed place, it will likely bite you.

So, don’t take it seriously. Your guinea pig is just scared.

2. Feeling Discomfort

Don’t be surprised if your guinea pig nibbles on your finger or that of your visitor while carrying it.

Usually, it takes some time for pets like that to adjust to a new environment, especially newborns.

At that point, it would be best if you put it down for a while.

3. Something Smells Delicious

No doubt, guinea pigs love fruits and vegetables and also have a good sense of smell.

They’ll likely bite your hands repeatedly if you just finished cutting fruit salad without washing your hands. That’s because your hands smell deliciously like their favorite food.

4. They Don’t Feel Well

There’s a chance that your guinea pig is not feeling well if it bites strangely. With time, you should have known that nibbling on your fingers or skin is a way they pass a message across to you. 

So, if you notice your guinea pig is looking pale, not eating, and biting, take it to the veterinary clinic.

5. They Feel Like Urinating

Note that a guinea pig will bite your fingers lightly if it wants to pee to prevent your cloth from getting soiled.

You’ll agree that this is reasonable behavior and they mean no harm. Holding them tight when you should put them down may cause a harder bite.

In this situation, that’s not their fault but yours.

Guinea pigs are not aggressive animals. They will only bite when they are not comfortable or trying to communicate with you.

There are a lot of different things your guinea pigs can bite. To prevent them from chewing poisonous substances, it would be best if you provide healthy ones only. 

Besides, a guinea pig’s dental health is dependent on what they bite regularly and how often they eat.

Even though guinea pigs bite a lot of substances, here are a few of them:

  •  Twigs such as apple branches, pear, birch etc
  • Paper
  •  Woodblocks
  • Cardboard 
  •  Sticks
  •  Hay sticks

  •  Toys
  • Sticks

Funnily, do you know that guinea pigs sometimes bite their owner? Yes, they do. Continue reading to know why they do this.

Why Does My Guinea Pig Bite When I Hold Him?

It can be disappointing to get bitten by the guinea pig you feed and play with every day. However, you need to know that guinea pigs don’t bite without reason. 

One common reason guinea pigs bite is if they need to pee and you are holding them tight. At that moment, they desperately need you to put them down. 

Another reason your favorite pet is nibbling on your skin could be that you don’t wash your hands after cutting fresh fruits and vegetables.

Since they love these plants and your hands smell delicious, guinea pigs will likely bite you based on this.

Sometimes, your guinea pig pets may be feeling unwell and irritated. During that period, they won’t want to be held because of their health status. Cuddling these pets forcefully could get you bitten.

Studying them for some time will give you a clue as to how they behave when feeling unwell.

Other times, your guinea pig will likely bite you out of fear.

Several factors in the environment like a gunshot, loud music, or fighting can scare them. They may hide in a corner as a result of this happening.

Trying to bring them out or holding them tight will likely cause an unpleasant result such as biting.

Study your guinea pig’s behavior to know when to hold them and when to let go. It will go a long way in preventing you from getting bitten.

What Happens If a Guinea Pig Bites You?

Guinea Pigs can be classified among the sweetest, most gentle, and friendly creatures in the animal kingdom. Sure, they bite once in a while but wouldn’t do that without one or two reasons. 

Keep in mind that guinea pigs rarely bite. And if they bite you, it would not cause a serious health problem. So keep your mind at rest.

However, this doesn’t mean you should not seek medical attention if you are bleeding or in pain. 

Your doctor will likely prescribe some antibiotics and give you a tetanus shot to prevent complications. If you’ve not taken a tetanus shot in the last ten years, don’t hesitate to do so.

Luckily, you cannot get infected germs and diseases from guinea pigs if they bite you because these bacteria and viruses cannot survive in humans.

Nevertheless, you should take quick action if a guinea pig bites you. With the right treatment, you wouldn’t have any serious health issues.

Is a Guinea Pig Bite Dangerous?

The quick answer is no, a guinea pig bite is not dangerous. But one thing is certain, you will feel mild pains that should go within a few days. 

Unlike other wild animals who are carriers of pathogens, guinea pigs will not infect you with diseases. You may bleed when bitten but it would not last long or require the service of a medical professional.

However, if the cut is deep or you feel it is infected, do not hesitate to contact your doctor.

Usually, they’ll give you a tetanus shot, painkillers, and antibiotics. 

Where Do Guinea Pigs Usually Bite?

Guinea pigs usually bite the fingers as it is the part they come in contact with most of the time. They also have a great sense of smell and an insatiable appetite which makes it easy to confuse your fingers for food. 

Ensure you wash your hands well with soap and water after cooking or cutting vegetables.

On the other hand, you should try wearing gloves for some time before feeding your guinea pigs or playing with them.

Whenever you are sure they can’t bite again, take the gloves off.

Identifying the cause of a problem is the first step to providing solutions to it.

Before you stop your guinea pigs from biting you, understand that there are underlying reasons behind this behavior.

Study them to know why they bite you and solutions will come naturally.

While trying to figure out ways not to make your guinea pig bite you, practice these 8 tips for a start.

1. Remove Sources of Loud Noises from their Environment

Guinea pigs love silence because of their calm nature. Hearing loud noises will create tension and fear in them. Carrying a guinea pig at that point is not advisable because it will likely bite you. 

To prevent this from happening, remove all sources of noise from their environment. 

2. Wash your Hands Regularly

After preparing your meal of fruits and vegetables, don’t forget to wash your hands very well. Guinea pigs have a high sense of smell and may confuse your hands for food.

Carrying your favorite guinea pig with an unwashed hand will likely make him bite you.

3. Provide Large Cages for them

Some animals don’t like to be in enclosed places. In fact, being in a solitary environment can make them bored and uncomfortable. 

Ensure your guinea pigs can roam around their cage. This will create a great difference in their behavior.

4. Allow them to Urinate

Free your guinea pig pet immediately when you notice it’s biting continuously. There’s a chance it wants to urinate and you are making this impossible by cuddling. Then observe what happens next.

5. Take them to the Veterinary Clinic Frequently

Once in a while, take your guinea pigs to the vet doctor’s office. They may be feeling unwell or have hidden bruises.

Being hurt can make your guinea pigs aggressive and bite you. But you wouldn’t know this unless you take them to the vet clinic.

6. Buy more Guinea Pigs

Animals enjoy each other’s company, just like humans. Keeping one or two guinea pigs may not be a good idea.

Ideally, five to ten of them is great as they will play together and feel less lonely.

Although there are other ways to make your guinea pigs feel lively, buy more, for a start.

7. Ensure they are Safe

Fear is another common reason guinea pigs bite. Whenever they feel threatened in their environment, you will likely get bitten. It’s a sign of defense.

Be careful while carrying them and avoid swinging them around. 

8. Prevent Mites in their Environment

Mites are the “number one” enemy of guinea pigs. If a mite bites your guinea pig, it feels uncomfortable and helpless.

And there is a transfer of aggression to you from them which is in the form of biting.

Check your guinea pig’s body for mite regularly. Wash their cages and disinfect their environment.
