How Long Does A Gerbil Live? All You Need To Know

Before adopting any creature as a pet, it is usual for you to be curious about its lifespan. Similarly, if you wonder how long does a gerbil lives, you have come to the right place. Wondering why? Gerbils are some of the most adorable creatures you will ever come across with their cute little bodies and long whiskers. Well, we will be discussing everything that you need to know about the lifespan of your little pet gerbil. 

The life duration of a gerbil varies depending upon which breed or species it belongs to. Do you know that it can live for anywhere from 1 to 8 years? Imagine how wide is the range of longevity of a gerbil!

The survival of this mini creature is largely dependent upon its food habits, living environment, health care, proper exercise, etc. Let’s now dig deep into the details about the lifespan of the gerbil. Let’s get started with the chief discussion!

How Long Do Gerbils Live?

Generally, the lifespan of gerbils varies from one another because of the factors of breed, living conditions, survival habits, food requirements, etc., that influence the total number of years for which this little rodent can live.

how long does a gerbil live

On average, the life expectancy of your pet gerbils may vary from 2 to 5 years. Since a majority of the people keep Mongolian gerbils as their pets, it is essential for them to realize that they have a lifespan of 2 to 3 or 4 years. 

However, the lifespan of a wild gerbil is in stark contrast to that of the usual domestic or pet gerbils. While dwelling in the wild, the gerbils hardly manage to live till a year.

This is because of the danger posed by the predators and carnivorous wild animals that are always on the lookout for hunting the small rodents. If, by luck, the gerbils succeed in escaping from the grasp of the predatory animals, they can survive for a period of 2 to 3 years.

Since the gerbils are hardy creatures and can quickly adapt to a variety of extreme or hostile circumstances, they are unlikely to die before the estimated lifespan unless a predator comes into the picture and creates havoc. 

Aging and the average lifespan of gerbils


If you wonder what the average lifespan of gerbils is, it is about 2 to 4 years, but if appropriately conditioned, they may continue to live for about 5 to 8 years. Their life expectancy is dependent upon the following lifespan factors. 

Lifespan Factors:

Breed Of The Gerbils 

A gerbil of a particular breed may have a completely different life expectancy from that of a fellow gerbil of some other breed.

Do you know that there are about 110 distinct breeds of gerbils? Each of them has different behavioral characteristics, habits, and life spans. So, while assessing the life span of a particular gerbil, it is essential to consider the breed to which it belongs. 

Type Of Environment 

The environment and the surroundings in which a gerbil is living influence its life span. If the aura around them is toxic and stressful, their life expectancy will drastically reduce.

Contrarily, if they dwell in a healthy environment, they are going to live for a considerably long period. 


Yes, exercise is a must for a gerbil to stay healthy! It is clearly understood why a pet gerbil has a longer life span than that of a wild gerbil. It is your responsibility to make your cute gerbil perform apt exercises so that they can stay healthy and insulated from any diseases. 


If a gerbil receives proper nutrition, that is, the required amount of foods along with ideal water intake, it will have a long life span.

The reverse will be the case for the wild gerbils because they won’t be receiving much nutrition as food scarcity always remains an alarming issue in the forests. 


The genes of a gerbil influence its life span in the sense that it acquires certain deadly diseases genetically. So, you should keep a proper check on the health condition of your rodent and consult a veterinarian, even if you notice minor changes in its behavior. 

Gerbil Life Cycle

While discussing how long do gerbils live, it becomes imperative to have a quick look at the life cycle of a gerbil.

  • After the mother gerbil gives birth to the pups, they take about 14 to 18 days to open their eyes.
  • After the passage of two days of the opening of its eyes, the gerbil’s ears start unfolding.
  • Gerbils stop suckling their mother’s milk after the passage of 28 days of their birth.
  • These rodents reach their adulthood phase after the weaning process stops and may even start living separately by digging distinct burrows away from their parents’ burrows.
  • After the passage of 3 months of their reaching adulthood, the gerbils become fit to breed.
  • After the gerbils cross 2 to 3 years of age, most of them start showing symptoms of aging.

Gerbil Lifespan in the Wild

Just as we had mentioned in the above section, a wild gerbil that originally hails from Mongolia can comfortably survive for about 2 to 3 years.

Unfortunately, such a thing becomes impossible because this little creature is subjected to several significant challenges in the wild.

These include lack of food, water, enhanced vulnerability to diseases, and attack of the ferocious carnivorous animals. What is worse is that the wild gerbils may even barely survive for 3 to 5 months because of the impending danger of death lingering in the forests. 

Gerbil Lifespan in Captivity

When gerbils are kept in captivity as pets, they usually live for about 3 to 5 years, and this may get extended to 8 years if proper care of their health is taken.

Since they get proper foods and nutrition and stay insulated from the predator’s attacks, the secured environment adds to their life expectancy.

The gerbil longevity is enhanced because the owner takes care of the cute rodent and checks its health condition to ensure that it is not afflicted with any disease.

Wild gerbils are deprived of this care and nurturing that the captive gerbils enjoy, thus accounting for the former’s long life span and the latter’s shorter life span.

Being a pet owner, it is usual for you to get concerned about your baby’s gerbil’s health. Now that you have got an inkling of your cute rodent’s life span, you may feel the urge or get a natural desire to enhance its long life expectancy.

You may wonder if such a thing is possible. But, do you know that you may contribute towards increasing the longevity of your dear gerbil? Let’s have a look at these tips. By following them, you can extend the life span of your rodent. 

  • Try to keep your gerbils either in pairs or clans instead of desolating them in captivity. 
  • At the time of breeding, always seek the help of a trustworthy and reputable breeder to safeguard the health and well-being of your gerbil. 
  • Train the gerbils from a young age and make them do specific exercises that would provide them with significant health benefits, increasing their life expectancy.
  • Before introducing a new gerbil to the cage, keep it isolated for the initial days till you are sure enough that it has not brought any kind of contagious illness with it. 
  • Make sure that proper hygiene in the living conditions of the gerbils is maintained. Clean their cage and bedding at regular intervals to ensure a safe atmosphere for the rodents. 
  • Feed your gerbil healthy and nutritious food that would enhance its health. If you are doubtful of feeding any specific food to the rodent, consult a vet to get the right advice regarding any food. Never overfeed your gerbil. Make sure that you are feeding it the amount of food that is suitable for its age. 
  • Avoid feeding your gerbils with any food that is high in sugar.
  • Make sure that you are providing your gerbils with some cool toys and stuff for them to play with so that they don’t sink into stress and feel bored by staying all day in the cage.

Do note that the above-mentioned tips won’t guarantee that your gerbil’s life span will be increased. However, following these habits will facilitate their health and increase their chances of longevity.

How To Tell If Your Gerbil Is Getting Old?

Every living organism on this planet exhibits certain signs that mark the beginning of the aging process, and gerbils are no exceptions in this case.

An old gerbil

It is crucial for you to note that some gerbils may show the signs of aging only after crossing two years of their lives, while others may not exhibit any aging signs even after reaching five years of their age.

It is all about how much care and nourishment they receive, and this, in turn, will determine their life expectancy. Well, let’s now have a look at the signs that echo the beginning of old age in a gerbil. 

Sharp Loss In The Muscle Mass 

Muscle mass, as the term suggests, refers to the total mass of the muscles in a gerbil. When young, a gerbil has a low muscle mass which then goes on to increase as they start maturing.

This gain in muscle mass will stop altogether once they reach old age. This loss in muscle mass denotes that your gerbil is aging and getting old. 

At the same time, the fat reserves in the body of the gerbil will also be used up. This is because they won’t have much appetite then, and therefore their bodies will attempt at using the already available fats stored in the body to extract energy.

If you weigh your gerbil on a proper weight machine, you will get an accurate record of its weight and realize the degree of the loss of its muscle mass. 


Alopecia is a common hair loss disease in humans, too, by which the victim of this ailment suffers from baldness. But, there is a subtle difference between the alopecia that humans suffer and that the gerbil’s witness.

Don’t worry, your gerbil won’t go completely bald just as humans do. But, the loss of hair in gerbils may stem from various reasons, and such a change in their physical appearance is an important indication that they are growing old.

If your gerbil has the habit of rubbing its furry body on the sides of the cages, it may lose quite a lot of body hair.

Moreover, if its body doesn’t get proper vitamins, alopecia may occur. This disease of body hair loss may also occur when your cute rodent starts getting old. If you notice that it is losing substantial hair from its body, try to accept the fact that your little pet is now growing old. 

Affliction Of Diseases 

Older gerbils tend to get afflicted with diseases frequently than the younger ones. If you notice that your tiny, great gerbil is falling sick quite often, know that it has stepped into old age. With the increase in age, gerbils’ immune system grows weak.

As a result, they quickly fall victim to the diseases of Tyzzer’s disease and respiratory infections. Heart failure is also a common mishap that occurs with older gerbils. 

Do note that all these signs are not exclusive to an old gerbil but may occur in any young gerbil, too. However, the old gerbils tend to get afflicted with these conditions more, at a regular rate. 

​​​Why Do Some Gerbils Live ​So Long?​​​​

Only those gerbils nurtured as pets live for an extended period, say, 3 to 5 years. The reason is that, while staying captive in homes, these rodents receive adequate nutrition and water that ensure their growth and maintenance of health.

Providing them with nutritious food helps in boosting their immune system, thereby shielding them from potential diseases and health hazards.

Since the wild gerbils cannot get access to proper food and always run the risk of being gobbled up by predators in the forests, they hardly live for a year. That is why pet gerbils live for so long while wild gerbils do not.
