I raised my first Leo from a baby and by the time he was full grown he was always out and about and I had him with me all day long. He loved walking around and exploring, even during the day. It depends on the individual. I guarantee you if someone tells you "this animal is mean," or, "this animal is boring," you can and just might find an exception.
Leos are by far my most loved animal
apart from beardies. And that's because mine was so lovable.
I had him for 5 years before my parents gave him away before we moved...I would do it again, but only when I could keep him for mine, or his whole life.
