Rick writes “It’s difficult to approach Dizzy without him becoming aware of it. And he’ll let you know he saw you by `talking’ to you, in a way that seems to convey emotion. If you move about, he will join the action by exploring his `terrarium’. When he gets hungry, he goes to his feeding point to have a lunch brake of an hour or so. While eating, he continues to react verbally to motion around him.” Link.
