Hi, I am a new owner and I wanted to see if guinea pigs will eat grass? I have read somewhere that they can, but on the other sites that they can't so, I am confused. The reason why I am asking that is that my father got a trimmer (a green corded like on the link) so I can use it to cut my guinea pig's an outside enclosure and then I thought of giving them those parts for a treat maybe? I don't plan to give it for a meal every day, the entire day, maybe just for one mIs? Are there any grass I should avoid? I really want to keep them healthy so I want to do the research before I do anything related to their nutrition, I think it is the most important part.
