Here are some things to expect in their lifetime, and some tips on how to enjoy your long-term dedication to your cavies.

But before that, we’ll talk first about guinea pigs.


What Are Guinea Pigs?

“Cavia porcellus,” or most commonly known as a guinea pig, is a domesticated rodent species that belongs to the cavy family.

Guinea pigs no longer exist in the wild; therefore, reproduction and mating systems are done domestically.

This type of animal prefers close contact and interaction with others. So it is a very suitable animal as a pet.


Factors Affecting The Lifespan of Guinea Pigs

The expectation is always present at first. If you are about to do something, you already have your expectations.

But don’t get those expectations too high, or it will only drag you down.

Here are some of the things that affect the lifespan of your furry pet:


#1. Life span

The question is:

How old do guinea pigs live?

Among other rodents, guinea pigs have a longer life span.

While hamsters and mice only live for a couple of years, guinea pigs could live around for an average of 5 to 7 years.

A longer life span means longer commitment and responsibility if you want your guinea pigs to live a happy life.

Although a guinea pig’s life span has no definite expiry date or ‘best before’ tag, there are some factors that could either shorten or lengthen your guinea pig’s life.


#2. According to breed

There are some breeds of guinea pigs that have a longer life span compared to others.

For example, hairless guinea pigs have a longer life span for an average of 7 to 8 years.

Long-haired ones have 5 to 6 years.


#3. Diet

How well you take care of your guinea pigs can affect your cavies life span.

Having a balanced diet can do miracles and lengthen your pet’s life.

I mean, if you would only eat nutritious foods which wouldn’t have a longer life?


#4. Other factors affecting life span

We can’t always be healthy, and we should accept that. The same goes for your cavies.

They can suffer from several health conditions as time passes. These conditions may be overcome when treated in the early stages.

Some common health issues your guinea pig may face are diarrhea, respiratory problems, scurvy, parasite, and skin problems.


#5. Guinea pigs are social animals

Guinea pigs are very social animals. They are happy to live with their same kind too.

However, you should first try to pair same-sex guinea pigs if you don’t want to have unexpected multiplication of expenses.

It is best to introduce a pair while they’re still babies, or they won’t get along that easily. ( please read here How do Guinea Pig get mites)


#6. Easy to tame

Guinea pigs are one of the animals that are easy to tame.

If handled with constant care and given an adequate amount of attention, the bond between you and your pet will indeed be built.


#7. Nutrition is a must

Like any other living thing, guinea pigs need their dose of nutrition too. Prepare their meal plans or plan their food.

Please make sure they are nutritious and not toxic for them.

Preparing hays and vegetables is an excellent way to go.

Some fruits like apples(do Guinea pigs eat apple), strawberries, oranges, and bananas(can Guinea pigs eat banana peel) may be too good for them, and overeating must be controlled.

Or else, unwanted diseases may start to rise. Instead of giving them a longer life, it could shorten them.


#8. Cages

If you plan to have more than one guinea pig, it is best recommended to build a larger one.

Unlike the typical ready-made guinea pig cages available in the market, which are smaller in size, guinea pigs tend to need a more massive floor to play with.

The cleanliness of their cages could also affect their health. The cleaner, the better.

The pens must be spacious enough for them to exercise their bodies and enjoy their life.

Anyway, if you don’t have time to build one for your furry pet, you can always find a durable, high-quality, and spacy home on sale. Opt for a double story cage for guinea pigs; my pet, Ginger, is very comfortable with this kind of home.


#9. Where to get one?

If you’re confused and want to get one yourself, guinea pigs are often available at shelters.

Some guinea pigs are available at your local shelters. But not all covers have them, okay?

Just try your local shelters first before heading out and buying one. It can save you some money, for sure.
