Aah, and a few more thoughts.

Spiders aren't the only ball morphs that can be neurologic. I've heard tell of a few sable and champagne combos that are off, and a few folks on here with regular womas say that they can wobble/spin as well.

Also, I have an albino male that I think may be low-grade neurologic. He doesn't spin or wobble, but he misses the rat more times than any of my spiders. He's been that way for a couple years now and has not gotten better or worse. (He does look at bit like what I'd imagine an albino woma would look, though .........)

And finally, I hatched a super pastel (non-spider) son from my bee who was very mildly neuro. He had a head tilt and I saw him spin a couple times, just like his dad. I have no idea what that means.
