Hi guys... We are the Chapman family and have decided to join this forum after acquiring a cage building obsession, thanks to our little one, Colbie. Colbie is now approximately 6 months old. She was 3 months old when we got her. She loves running laps in her cage, popcorning, whistling and making all types of noises. We never expected a guinea pig to be like this and we just love her so much.
