Guinea pigs can eat collards, as they are a delicious addition to their varied diet and are an important part of their staple vegetable portion. However, they should only be given in moderation, as they may cause gas or bloating in some guinea pigs and can contribute to the formation of bladder stones due to the oxalic acid content. It is important to balance collards with other leafy greens and monitor your guinea pig for any adverse reactions.
