I have a male and female spider and I have never seen the wobble in them yet. I know it can come and go or come and stay. They are both eating very well and putting on weight just like they should. The female was my only problem eater when I first got her. Now she is pounding mice and rats like there is no tomorrow. It is sad that this morph has such a bad problem. If my snakes start a really serious wobble I wouldn't think twice about not breeding them. What is baffling is that nobody knows what causes it and why it is mostly happening with Spiders.
