Guinea Pig Life Span

The Cavy, also known as the Guinea Pig is from South America origin. Starting from mountains to grasslands, they inhabit a variety of terrains. They often live inside the burrows they prepare for themselves. Sometimes, they also live inside abandoned burrows made by other animals.

Since guinea pigs are nocturnal feeders, they rely on various forms of vegetables to survive. Surprisingly, guinea pigs and pigs have one thing in common. The female guinea pig is called a sow while the male is called a boar.

As guinea pigs are more robust than their smaller cousins, they can live longer than hamsters that stay alive for around 2-3 years. You can expect a guinea pig to live for 4 to 8 years. There are types of guinea pigs that have differences in life span.


Abyssinian Guinea Pigs

Abyssinian guinea pigs live for approximately 5 to 6 years if they stay in a happy and safe environment. As they are known to be excitable, if you do not look after them properly, they’ll get stress-related illnesses.

Peruvian Guinea Pigs

Peruvian guinea pigs also live like the average guinea pigs of other breeds. However, there are also categories of Peruvian guinea pigs.

There are short-haired guinea pigs and there are long-haired ones. The ones with the long fur cannot groom themselves as the short-haired ones do. If you don’t groom the pets daily, the fur can get tangled with each other which can produce a thick mass. This can later, cause skin problems and infections which can be a threat to your pet. Thus, life expectancy can reduce while leaving you with sorrows.

Young Peruvians may also face problems suckling their mother’s breast due to the long hair issue. This can lead to malnourishment and slow growth.

Fun Fact: The longest living guinea pig in the world, according to Guinness Book of Records was Snowball. He lived in Nottinghamshire, England who died in 1979.

Weight and Size

Though the weights of guinea pigs may differ, the average weight a male guinea pig holds is 800-1200g. On the other hand, the female weighs slightly less though. They have around 600-900g of weight.

How Long Do Guinea Pigs Live as Pets?

The life expectancy may increase if guinea pigs are kept as pets. Into the wilds, the life of guinea pigs remains in threats. Wild animals are always on their backs to hunt them. The weather and climate also have effects on their health.

If you take good care of your guinea pig then it can have a healthy life. But then again, if it falls on wrong hands, the guinea pig can have a short life too. To take good care of your guinea pig, you should study their life cycle, diet as well as their breeding method.

The Guinea Pig Life Cycle

You’ll notice that the newborn guinea pigs are fully haired. They keep their eyes wide open while their eyes start to show. This is the stage of precocious (early development).

A guinea pig usually has 65 days of gestation period. The sow (female guinea pig) becomes ready to give birth to babies from about 2-3 months. At this stage, the body weight usually reaches to 500 grams.

Surprisingly, the young ones suckle from their mother just for a couple of days only. Within a very short time, they start to feed on solid foods. Gradually, they feed on the mother’s milk and solid as well as solid foods for around 3 weeks.

At this stage, you should separate their mothers and sisters from the young ones, as they’re close to sexual maturity.

You should keep in mind that guinea pigs grow very fast. In the time of birth, their sizes are around 8-10cm. They reach to 15 to 20cm by 8 weeks. After 8 weeks have passed, the growth will slightly pause for a while. The guinea pigs will grow slower after that until they reach 14 months.

Guinea Pig Genetics and Breeding

If the guinea pig’s parents and grandparents had a long life, then you can expect the guinea pig to have a long life too. At least that’s what genetic science tells us. However, the expectancy can still fall as the gene pool gets weakened. This can happen due to the nature of the cross and selective breeding patterns in guinea pigs.

So it is always preferable to produce a ‘pure breed’ all the time. Breeders should look into this matter very seriously.

Inbreeding can cause lots of gene-related problems. Inbreeding can cause problems like

  • Weaker immune systems
  • Smaller size
  • Physical Deformities
  • Decreased Fertility
  • Overall health problems

All of these can lead to infections, smaller litters, and increased mortality during birth. However, you should always stay connected with pet stores and vets. If you take good care of your ‘furball friend’, there’s a chance of having a long and happy life.

Diet and Health

You should make sure that your guinea pig is having a friendly diet. Having the best diet can increase the life expectancy of your pet. To make sure the guinea pig stays healthy, offering fresh food using quality foodstuffs is a must.
