Yes, guinea pigs can eat fresh blueberries occasionally as a treat. Limit it to a couple of berries at a time, as blueberries are high in sugar and must never replace leafy greens and vegetables in their diet.
Benefits of Blueberries for Guinea Pigs
- Highly nutritious treat — Blueberries are rich in antioxidants that help protect guinea pigs from cell damage.
- Good source of vitamin C — Required daily as guinea pigs do not make their own vitamin C. Supports immune health and prevents scurvy.
- Tasty and well-liked — Most guinea pigs enjoy the sweet flavour, making blueberries an easy healthy snack.
