Destructive Guinea Pigs

Are Guinea Pigs Destructive? [Know About Their Bad Behavior!]

Guinea pigs are gentle little creatures that are normally calm, usually playful, and generally friendly. They are a common family pet that’s loved by both children and adults.

They like being neat and they’ll groom themselves often. But sometimes they will throw hay all over, strewing it everywhere and making a mess of their environment.

They will also chew on anything and everything which would make you wonder if these lovely balls of fur could be destructive at times. Well, let’s look into that a little deeper.

Are guinea pigs destructive?

Guinea pigs have a tendency of being destructive at times more so when you don’t keep an eye on them. They will chew on cage bars, things inside their cage, clothing, household furniture, electric cords, and anything they can get their teeth on. Though it’s their nature to constantly chew on things, sometimes it can be triggered by something affecting them. It could be due to loneliness, inadequate exercise, depression, or a lack of space.

Destructive guinea pig behaviors

Guinea pigs have some destructive tendencies like:

Chewing on things

Guinea pigs are chewy animals that need to chew constantly to wear down their ever-growing teeth. Their teeth keep growing and if they do not get worn down they become painful which could lead your pet to stop eating.

If they do not have things to chew on, they will begin chewing on everything inside their cage from their cage accessories and cage bars to their hideys and bedding.

Sometimes they will chew on things outside their cage like your furniture, carpet, electric wires, etc. Also, if they don’t have enough space to fit into a place, they may chew around it to make the space bigger for them to pass through.

Due to their cleanliness, guinea pigs will tidy themselves up every now and then. Sometimes they end up overdoing it and this can be dangerous for them.

As they lick up their hair, it’s usual to swallow some of it. Sometimes the hair that falls during grooming may get into their food and water.

The hair can pass through their digestive tract with hay and water and be excreted, but at other times the hair forms lumps in their stomachs or digestive tract. These lumps get stuck there and cause a blockage that makes them unable to eat or drink.

This is what we call the formation of hairballs and it’s dangerous for guinea pig health.


Just like over-grooming, barbering involves guinea pigs and their hair. Barbering is where guinea pigs chew on their hair or that of their fellow cagemates.

Barbering is usually excessive because the barbered guinea pig is left with bald patches on their skin.


Overeating is another destructive tendency where guinea pigs will eat more than their normal share of feed. Eating a lot of hay is always okay, overeating becomes a problem when they are ingesting more veggies and fruits.

Fruits, for instance, will contain high sugar content which will lead to teeth damage, fast weight gain, obesity, and diabetes.

Reasons that lead to destructive behaviors in guinea pigs

As we said earlier, destructive tendencies are usually brought about by some triggers because naturally, guinea pigs are calm and gentle. Triggers may include:

Inadequate exercise

Lack of mental stimulation

Did you know that your furry pet was a smart intelligent animal that requires frequent mental stimulation? Guinea pigs require something to stimulate their brains regularly.

Not enough hay

Guinea pigs require a lot of hay at all times. It’s recommended to provide hay as 80% of their food.

These pets have a delicate digestive system that needs hay for fiber to aid in digestion. Hay can also be part of their bedding.

Seeking attention

Age and gender
