Awww, sounds like guinea heaven!!

When we had our guinea pig Klein Hans (all black), along the garage we planted a lettuce garden and fenced it in with chicken wire. We'd just plop him in there and let him have fun. It was shady from the overhang, and full of lettuce for him to eat. He LOVED it! Of course! He also LOVED to eat the clover growign the the grass, but he'd never eat the white little flower- just the stem.
