My daughters two guinea pigs, Dillon and Charlotte seem to love being held or lying down on your chest when you are watching TV or on the computer such as I am. They will spraul out and put there head down and do something like a not so loud churping noise when you pet them behind the ears, does this mean that they are comfortable and enjoying the attention? Dillon when you pet him will put his head up next to you when you are petting him and cuddle or it seems like he does, is this for real a cuddle from a guinea pig?
