Yes, guinea pigs can eat collard greens, a leafy green vegetable packed with nutrients. Most guinea pigs enjoy the large, crunchy leaves, which can be fed whole or in pieces. Collard greens are high in vitamin C and calcium, but because they also contain oxalates, they should be offered in moderation alongside a variety of other fresh vegetables.
How to Safely Feed Collard Greens
- Frequency: A few times a week, mixed with other leafy greens and vegetables.
- Quantity: Small amounts due to high oxalate content.
- Preparation: Wash thoroughly before feeding to remove any dirt or pesticides.
- Portion tips: Feed whole leaves if your guinea pig prefers, but chopped is also fine. Mix with a variety of other vegetables for a balanced diet.
