Well, our Lucius is a bit different. We received him in adulthood. It took us YEARS for us being able to touch him. And even now he is not easy going when it means he's away from his cage. He's a bit of a 'home-body' and enjoys his routine (i.e. always goes to bed early, gets his food at the right time etc). He is extremely loud: 1) as alarm when people pass by outside or inside the home and 2) when he's hungry. But he has a very unique personality. He always alerts the dogs of "danger" before they even have a clue. He sticks his tongue out when he's petted on the head. He tricks the dogs into eating food he doesn't want. He loves juice. Through his different noises I can always tell what he is doing.
