Share it with Your Friends!

In this article, we will learn some of the reasons why some guinea pigs can be lazy.

Typically, guinea pigs are highly active pets. So you’ll see them always playing and running around in their cage.

However, they may take little naps every now and then or just lie down because of many reasons such as relaxation or boredom.

Sometimes guinea pigs can also act lazy because of internal problems.

Let’s take deep dive into each of these reasons why and discuss the possible solution!

Reason #1: Relaxation

Guinea pigs enjoy being lazy for a variety of reasons, one of which is that it allows them to relax.

When guinea pigs feel at ease, they will lie down for a long period of time. If you look at their feet while they’re lying, you’ll see if they’re fully extended.

Since they trust you and their surroundings, they’re happy to lay down and relax quietly.

Also, they are so active during the day. Hence, guinea pigs have a tendency to laze around at night.

However, this laziness can also be due to tiredness.

Reason #2: Tiredness

In good spirits, the guinea pigs run around their cages. You may notice him circling around and around, continuously changing its path.

This makes your guinea pig sometimes tired. And due to that tiredness, it may become lazy.

However, being lazy due to this reason should not stay much longer. But what about your guinea pig getting bored?

Reason #3: Boredom

It is not uncommon for a guinea pig to be lazy when it is getting boring.

If they don’t experience something new in a while they get bored. They may simply lie down until they feel like doing something else.

In this case, you can give them new toys to play with or take them to walk with you. 

If you want your guinea pigs to enjoy their natural instincts of exploring, chewing on, hiding, and playing without getting bored, you should provide them with exciting toys or challenges.

Reason #4: Stress

Your guinea pig’s behavior will show signs of stress or depression.

There are many symptoms that indicate stress in the guinea pig, such as head tossing, fidgety behavior, and laziness.

 A guinea pig that is depressed will become slow-moving and lack enthusiasm.

If your guinea pig is behaving in either of these ways, you may wish to see a veterinarian.

However, being stressed for a long time can lead to obesity as well.

Reason #5: Obesity

In obese guinea pigs, fatty pads can be found all over their bodies. Their internal organs, including the heart, can develop fat deposits, which can lead to laziness.

This can cause them to grow unfit and decrease their exercise tolerance.

If your male or female guinea pig weighs more than 900 and 1,200 grams, they can be lazy.

Reason #6: Insufficient dietary intake

Guinea pigs are known for their uncontrollable appetites. Another reason for being lazy can be insufficient nutrition in their body.

If your guinea pigs aren’t getting the correct nutrients and you notice them laying down a lot, it could be a sign of a more serious health issue.

Weight loss due to lack of nutrition makes them weak and they become lazy.

Lack of sufficient nutrients makes it difficult for your pet to carry out their daily routines.

As a result, they’ll simply lie down and rest.

Insufficient dietary intake can also cause vitamin deficiency in your pet’s body.

Reason #7: Vitamin C Deficiency

Lack of vitamin C in your guinea pig may make it weak and therefore lazy.

To diagnose vitamin C deficiency, you should take your guinea pig to the vet as soon as you discover that they are lethargic or sleepy most of the time.

Your pet guinea pig’s excessive fatigue or lethargy could also be caused by the food they’re eating.

Make sure your guinea pig gets food rich in vitamins and minerals, including vitamin C.

Due to insufficient vitamin intake, your pet may build some internal disease as well.

Reason #8: Internal Disease

Guinea pigs can suffer from the following:

  • Respiratory infections
  • Diarrhea
  • Scurvy (vitamin C deficiency)
  • Tumors
  • Abscesses related to infection
  • Urinary issues
  • And infestations by lice, mites, or fungus parasites.

When your guinea pig fights these diseases, it becomes weak and therefore seems lazy.

So, visit a vet to check if your guinea pig is going through some of these diseases.

Reason #9: Genes

Guinea pigs’ personalities are usually dictated by their DNA.

If a guinea pig carries a lazy gene, it will be lazy no matter what.

In addition, the environment in which the pet guinea pig is raised has an impact on its personality.

A small environment that lacks stimulation can lead to the development of laziness, even in animals with hyperactive genes.

Reason #10: Serotonin

Low levels of serotonin in guinea pigs may be the cause of their laziness. 

It is a neurotransmitter that regulates mood, sleep, and hunger.

Depression and lethargy can happen when serotonin levels are too low.

This can happen if guinea pigs lack activity or aren’t provided enough to play with.

Reason #11: Lack of Playmate

Educative and challenging toys are a favorite pastime for guinea pigs. Among their favorite things to play with is a variety of chew toys, balls, tubes, mirrors, and so on.

So, if you don’t provide the toys and playtime it requires, your pet may get bored and therefore lazy.

Also, as a pet owner, if you don’t play with your guinea pig, your pet may get bored.

Make sure you give it your time and toys to keep occupied for hours at a time.

Reason #12: Peaceful Environment

Guinea pigs are known to relax when they feel safe enough, as already mentioned in this article.

If they’re comfortable enough to sleep, it signifies that you’re offering a quiet environment.
