Guinea pigs should eat celery stems as they are a delicious addition to their varied diet and provide essential leafy greens. Additionally, celery stems are low in calcium, which is beneficial for guinea pigs. However, it is important to chop up the celery stems before feeding them to guinea pigs due to the long, indigestible strings, and to feed them in moderation to avoid any digestive issues.
