Should I give my guinea pig supplements?

Guinea pigs, like humans, don't manufacture their own vitamin C. Your guinea pig needs fresh foods high in vitamin C to remain healthy. Some fresh foods to include are red and green peppers, kale, parsley, broccoli, cauliflower, strawberries, kiwi, kohlrabi, red cabbage, orange. You can also give him a liquid vitamin C children's supplement. Liquid is easier to administer than tablets.
