Your guinea pig needs a variety of foods to keep happy and healthy. Start with a high-quality, nutritionally complete guinea pig pellet. Be careful with the amount of pellets you fed your pig to keep him from getting obese. Give your pig fresh, leafy greens daily such as spinach, kale or romaine lettuce. Add other vegetables such as carrots or squash for extra nutrition and to keep the teeth trim. A small piece of fruit can make a nice treat several times a week. Your guinea pig will also need timothy hay to help his digestive system work well and all that nibbling keeps his teeth healthy. Guinea pigs cannot manufacture vitamin C on their own so you must provide this important vitamin through his diet. And of course your pig needs access to fresh, clean water at all times.
