Does anyone know this answer, I had two male guinea pigs whom I gave to a friend for her classroom, the children are not allowed to handle them, they only feed them and all was fine, however, yesterday they found one of them dead, he was upside down. I was told they always had water and plenty to eat so I do not think this was in anyway neglect. My question then is it possible for a guinea pig to just be heart broken, you know like he miss his old environment? They are in a C&C cage and have plenty of room to run, but he was always in his house, so I wonder perhaps he was just ill and no one knew. Any answers would be nice, its sad. :sorry:
