#1. Uncomfortable handling

Your guinea pig may be feel being mishandled and uncomfortable. It could bite you if he doesn’t like the way you are holding him.

Also, some of your cavies do not want to be carried while going up and down the stairs or walking it around, because this might feel them very unsafe and insecure.

And this usually happens when you went from the kitchen or when you grab some salty snacks before holding your pet.


#3. Too much noise

Sudden and too much loud noise would be one of the reasons why, because your cute piggy is frightened.

Other commotions such as thunderstorms, loud bass music, and even a vacuum cleaner could make it startle and panic.

My American guinea pig Ginger is frightened of the vacuum cleaner’s sound.

He would popcorn− hop and twist into the air like he is very pissed and annoyed. And when I hold him, he just bites me like he is under an anxiety attack.

I ask myself why is my guinea pig biting me? Then I just realize that guinea pigs don’t want too many commotions.


#4. Fear

Your cavy would be terrified if it is not familiar to the person who is holding them. It would also cause your guinea pig to panic and would be very abusive.

This might be their way of saying that they don’t want to be petted by another person but you because they do not trust them.


#5. Discomfort

If your cavy is feeling pain and sore in her body, it wouldn’t want to be petted and held because it is painful if you would touch her and would cause them to bite you.

Some discomfort that your guinea pig might be experiencing are bruises, sprains, skin irritation, arthritis, or other possible sicknesses your guinea pig may have.


#6. Moody

It is very unusual for a guinea pig to bite its owners; it is not what they are. Your lovely pet wants to be cuddled and feel loved and climb into your hands without hassle and fear.

If they ever bite you again, then this would be a signal that they are in their moody state and want to put down back in their cage.

My cavy, Ginger, sometimes be moody when I cuddle her; she bites my arms or hands. So carry her back into her little house. But even with such behavior, I still love her.

Things To Do If Your Guinea Pig Bites You

If your cavy bites you, you should make sure that you washed the wound immediately and adequately.

Try to wash it with running water and soap; in this way, you’re sure that it can help prevent infection from injury.

I recommend you to use some anti-microbial ointment for faster healing and for you to ensure that no bacteria is building up to result from infection.

If your cavy bites you seriously and causes too much bleeding, apply pressure on the part in about 5 to 10 minutes with a clean cloth or bandage.

Good thing guinea pigs don’t carry a high risk of rabies. However, cavies can transmit other infections, so you should be careful in carrying your adorable pet.



Guinea pigs are lovely and friendly rodents, but it doesn’t mean that you don’t have to consider things on how to handle and take a good care of them.

It is imperative to consider several things that may help you to build and gain the trust of your cavy to avoid them from biting you. And if your lovely pet is becoming aggressive, it is advisable to take it to your vet.
