How long do guinea pigs live?

It is important to note that a guinea pig is not a hamster. A lot of pet owners do not know the difference and think these animals have similar life expectancies. However, they are actually quite different! There are several breeds of hamsters and this can affect how long they live, but a normal hamster can live for two to three years depending on how they are treated.

Ways to increase a guinea pig’s life expectancy

Fresh food: As with any living creature, providing your guinea pig with fresh food is one of the best ways to increase life expectancy. Make sure that uneaten food, like greens, is removed from the cage within 24 hours so your guinea pig doesn’t eat food that is no longer fresh.

Purchase a comfortable cage: Just like humans, guinea pigs like to be comfortable, too! A good recommendation is to provide at least 7.5 square feet for one guinea pig and 10 square feet of living space for two guinea pigs. The more space you provide them, the happier your guinea pigs will be.

Absorbent guinea pig bedding: Kiln-dried pine shavings, paper bedding, or fleece are a few suitable options to choose from. In addition, it is important to change guinea pigs’ bedding on a schedule so you can prevent odor or ammonia build-up. It is recommended that you change bedding at least once a week, but every three to four days is better.

Provide materials to chew on: In order to stay healthy, pigs need to keep their teeth ground down. Therefore, make sure that you buy your furry friend chew toys or pet-safe wood blocks.

Do not allow females to become pregnant: The pregnancy and birthing process is hard on female guinea pigs. In fact, one in five females that are bred will die as a result of complications during pregnancy or birth.

Locate a good veterinarian: It is important that you be proactive and find a good vet before your guinea pig has a medical issue. Even though guinea pigs do not require any vaccinations, it is recommended that you bring them to a veterinarian at least once a year.

Don’t mix pairs: Getting more than one guinea pig is a great way to increase longevity for guinea pigs. Just like humans, guineas are sociable and enjoy having a community around them. Nevertheless, make sure to keep guinea pigs of the same sex together or pairs that have already been spayed and neutered. As mentioned before, it is not good to have an unplanned guinea pig pregnancy in your household.

Can guinea pigs live alone if one dies?

Guinea pigs prefer to live in pairs or even small groups, but what happens if one of your beloved pets passes and leaves a friend behind? One option is to get another animal and introduce them slowly and carefully. However, if you’ve decided not to keep these beasties around anymore, you’ll have to invest in caring for your sweet piggy extra well.
First, watch for signs of stress and depression, like not eating, and take your guinea to the vet right away if he starts skipping meals or not drinking. Next up, increase other forms of stimulation with toys and playtime. While you’ll never meet the same needs as his bestie, dialing up the attention during this difficult time will probably help both of you heal. Lastly, keep everything else the same — feeding schedule, cage, and the rest of the household. Definitely don’t add another pet at this time, as that will only cause him further stress.

As you can see, getting a guinea pig is a great option if you are looking for a pet with a life expectancy of five to 10 years. You play a role in your pet having a long, healthy life by giving your guinea pig a great house filled with nutritious food and lots of friends. Care for your guinea pig just like you would a young child and you will do fine as a guinea pig parent!
