I am a little confused about how this works but hopefully I am doing it right. I have five guinea pigs, but I foster too so occasionally I have more than five. I have three girls and two boys of my own. The girls: sugar, button, and skittles. The boys: ginger (thought he was a girl for a long time) and steven. During the day they have a huge play pen (split up by gender). I am still wondering about the forums but I can't wait to get to know some fellow guinea pigs lovers
