Hi I really don't know how much, and what veggies to feed my guinea pig per day. At the moment I mostly giver her carrots, and romaine lettuce with her hay, and pellets, and sometimes she eats broccoli. I've tried to giver her cucumber, celery, and bell peppers but she doesn't like any of those. I've herd spinach is good but I don't have access to spinach. Should i just keep giving her carrots, and romaine lettuce or find something else?
