1-2 times a week
Guinea pigs can eat mandarin oranges as an occasional treat due to their high sugar and acid content. It is important to limit their intake to no more than 2 sections per week and to provide the fruit in small amounts to avoid digestive issues and potential tooth decay. Overall, while mandarin oranges can be a flavorful and tasty treat for guinea pigs, it is important to exercise caution and moderation when offering it to them.
