I think what everyone is trying to say is that your problems revolve around prey that is too small and the ball being hungry. She's most likely more active because she is hungry. She didn't constrict because the prey was too small. After being told by a dozen people that you need to up the food size, if you're still not concerned about her diet, then, well, you at least SHOULD be. You just asked this question, meaning that you apparantly weren't concerned about this before, just now, and, you're just now feeding a pinky, so, yes, it does go hand-in-hand. Feed the right size prey and your "problems" should all disappear.
