Have you ever had a pet guinea pig? If not, I have fun facts about these common household pets. First off, if you plan to get a guinea pig, make sure to give them much attention for about 5-8 years, that is their average lifespan. Guinea pigs are herbivores, they love fruits and veggies, especially carrots! They also eat a variety of pellets, and timothy hay. Make sure not to overfeed them fruits and vegetables because it can eventually led to problems, like sores around the mouth. Guinea pigs are very easy to handle and are very lovable. They also usually stay clean, and rarely need baths. Although, they need their nails clipped about once a month. They are very funny, and like to make many different sounds. They get along with other animals, and they prefer to live with another mate. They are great pets to have!
