How long does a guinea pigs last?

The average lifespan for a guinea pig is about 5 years, however there have been guinea pigs who have made it to the age of 13. Therefore, how long your guinea pig will last can vary quite a bit; from only 4 years to their teens.

You are correct but I heard from the vet that a Guinea Pig can last for at least 8 years if you take really good care of them.
