I checked the piggy shopping list and (fresh) green beans are on it. For some reason when I got home and put some in the food bowl, after removing the bean part (afraid of choking) I typed in "green beans guinea pig" into Google and it seems like no one knows if they're OK for pigs or not. Some sites even used the word "poisonous" so I leapt back into her room and snatched the beans out before she got to them until I could check with you all and see if anyone knew anything...
