Your guinea pig needs a variety of foods to keep healthy and happy. Start with a high-quality guinea pig pellet. Purchase the pellets from a pet supply company with high turnover so you know the food is fresh. Add fresh, leafy greens such as romaine lettuce, spinach or kale. Feed your pig crunchy vegetables such as carrots or squash for variety and added nutrition. Your pig will enjoy small pieces of fruit as a snack such as apple slices or chunks of strawberries. Guinea pigs can’t manufacture their own vitamin C so ensure that some of the fruits and vegetables you feed your pet are high in this vitamin. Your pig will also need lots and lots of timothy hay. This hay helps your pig’s digestive system work properly and all that nibbling help keep his teeth trim. And don’t forget to provide fresh, clean water at all times.
