Guinea pigs can eat lettuce, including butterhead, Boston, and Bibb varieties, as a delicious addition to their varied diet. However, it should only be fed in moderation as part of their staple vegetable portion, with a minimum of 5 leafy greens making up this portion. Overfeeding lettuce to guinea pigs can lead to digestive issues and potential health problems, so it’s important to balance their diet with a variety of other vegetables.
