Hello everyone! New to the forum, just joined today. Looking for advice on guinea pig cages. We have two crazy girls, sisters, who were born last May. Their names are Goldilocks and Cinnamon. I will have to post pics next time. But I am considering the C and C cage and wondering if I could buy or make a 3 x 3 grid for them. Would that be enough room for them? We need to be able to cover it because we do have other pets, but also, these girls have a habit of getting on top of their house and I am afraid they would jump out. I look forward to coming in and learning more about piggies in this forum!
