Actually it was your bee that made me think of it(Well, that and the fact that my female normal changed color a last week, ha!)
It does seem to me as though spiders are still a bit overrepresented, though I do appreciate those who posted links/pictures of other morphs undergoing the change ... So it's definitely not just spiders!
Bones, did anything "unusual" happen to your snake before he started changing colors? Any bad feeders or feeders from a different source maybe?
