Guinea pigs can eat winter squash in moderation as a treat because it can be high in carbohydrates, which can predispose them to bloat, digestive upset, or enterotoxemia. Additionally, winter squash is high in sugar, which can lead to obesity, so it should be avoided as part of their main diet. Overall, while guinea pigs can consume winter squash, it should only be given in small amounts to prevent potential health issues.
