Importance of Vegetables for Guinea Pigs

Guinea Pigs are herbivores and need a balanced diet with various nutrients. Vegetables provide them with vitamins, minerals, and antioxidants. They also contain fiber, which helps digestion and keeps the guinea pig clean.

Vitamin C

Guinea pigs need vitamin C to maintain a healthy immune system. You can give them fresh produce, including fruits and vegetables, to provide this critical vitamin. Along with hay, fresh water, and some pellets, these animals will be healthy if given a diet with plenty of vitamin C-rich food.
