It's a neurological issue. I'm sure there are a few cases out there where it effects them enough to have a health decline. Along the same as Spiders.

I'm still hoping it won't come out as much once she settles in.

I didn't know anything about the Jag issue until after I got my girl. So far she has never showed any signs of have a "wobble" or problem.

Another Jag issue. If you breed Jag x Jag all the supers or BELs will be still born or die soon after they hatch.

Good luck with her and keep us updated.
