I really don't think guinea pigs get enough credit. I sometimes have them through in my bedroom for laptime if I'm watching tv or studying just to spend some time with them and give them some extra veggie treats. I always know when CheesyPuff has had enough because he starts moaning. Well last night I was in our bedroom with him and my OH was in the spare room where their cage is and CheesyPuff had decided he wanted to go home. So I put him down on the floor while I folded up their fleece and before I knew it he had dondered voluntarily through to his room right to his cage and was hanging about there waiting for my OH to put him back in. Thought it might have just been a one off but he did the same today. I'm such a proud parent! lol.x)x)x)
