There's a list of foods guinea pigs can eat at The Guinea Pig Hutch, which has a "question foods" section for foods they just don't know enough about to say if they're okay for us to eat or not. For some reason, a lot of the question foods are Asian fruits. We don't know why. If anyone knows which ones are safe, please comment! We'd love to try lychee or mangosteen if they're safe for us. One of the few Asian fruits that's on the safe list is Asian pears, which we're reviewing today.
Asian pears are delicious! 5/5 stars!
