LOL! yes, guinea pigs do like hiding! My oldest guinea pig - Cadbury, is a real people guinea pig! I can put him like 5 metres away from me, and he'll sniff me out, and come and sit in my lap, it's really sweet!
horse_1987 - Me and my father are going to make my pigs a morant hutch. You often see rabbits in them, they're like a triangular prism, and they're a wooden frame with wire around it, and I'm going to put them on the grass in it !
