oh he loves that box. It gives him security. I've noticed that he sleeps in it at night sometimes. He also uses the substrate as pillow, pushs it up with his hands and lays his head on it. He is incredible smart. I don't handfeed him and i don't touch him at all. I domplay with him in a way, that i make him to solve problems to get his food. But believe me, an Argus monitor is the meanest of allmonitor lizards and i would never hand feed him. His teeth are incredible sharp. As i said, i throwm a chicken in...he bites in chickens leg, shakes his head one time and that separates the leg from the chicken...When he gets a hold on your hand you can say good bye to your fingers. When he was new he smashed his tail against you, when you even came close. He still pumps himself up when i come closer but is calmer now. There are rare cases of tamer argus monitors but in general they are aggressive and i would not take the risk. He even want eat the cat whenever she comes into the room....just to give you an impression. I think its cool to watch him and make funny intelligence games with him but it s definitly no cuddle pet.
