Sounds like a normal ball to me. I've got some that feel the need to ALWAYS be into stuff and be nosy while I'm in the room. Others simply want to be left alone and have no problem letting me know I am bothering them. As long as she is eating and growing fine, I wouldn't worry too much. Some are just a little more active/nosy than others.

What kind of fuzzy are you feeding her? Rat? Mouse? ASF? Other? If that is her in your avatar, you might try bumping her up a prey size. I large rat fuzzy every 5 days would be a minimum for her in my opinion.
