This a more "philosophical" question than a practical one anyway... I haven't been handling Ginger much lately because I've been busy but I had to grab her the other day so I could clean her cage. She open-mouth hissed at me when she saw me coming but didn't do anything once I touched her. She's never ever once tried to bite me but she can hiss and rattle for all she's worth. Anyway WHY doesn't she bite or squirm after she takes all that effort to try and scare me? What's the point of growling, hissing, rattling, and holding her breath if she's not going to fight til the death or at least try to get away?
