The lifespan of a guinea pig depends on a number of factors, including:
* Genetics: Some guinea pigs are simply born with a longer lifespan than others.
* Diet: A healthy diet can help to extend a guinea pig's lifespan. Guinea pigs should eat a diet high in hay and fresh vegetables, and low in pellets and treats.
* Exercise: Exercise is important for guinea pigs' overall health and can help to extend their lifespan. Guinea pigs should have plenty of space to run and play, and should be encouraged to exercise regularly.
* Environment: A clean, safe environment can help to keep guinea pigs healthy and extend their lifespan. Guinea pigs should live in a draft-free enclosure with a comfortable temperature and plenty of bedding.
* Veterinary care: Regular veterinary care is essential for keeping guinea pigs healthy and extending their lifespan. Guinea pigs should be seen by a veterinarian at least once a year, and more often if they are sick or injured.
By following these tips, you can help your guinea pig live a long and healthy life.
