I believe that not having a house simply causes the animal more stress. Guinea pig's only defense is run and hide, so where can they possibly use there defense mechanism without the house? If you want, you can simply not use hidey houses. Many people do it that way. that's just not what i think is right. My Cocoa has a hidey house in his cage 24/7 and I can walk past his cage anyday and he'll come up to investigate, or be eating or lounging. He never runs into his house now. Yes, he sometimes does rest in it because my brother is a moron who keeps the TV volume up all day. But he does come out for people he knows.
