I have a STO. She was already quite tame when I got her, really curious and she jumps right onto your hand when you hold it out for her. But when I have her out she's really active and running all over me, from what I've heard from others that's pretty normal.
Mine doesn't like dry cat food so I offer wet cat food sometimes. But I usually give her raw meat (I have frozen meat meant for cats), adult and pinky mice, eggs, fruit and vegetables (she loves broccoli) and lots of insects. Meal worms, beetles, crickets, roaches, grasshoppers and so on. She loves to catch them in her cage.
