Thank you so much Sukie! That was a fabulous summary, but at the same time, a complete look at neural crest "defects". I highly suggest that ferret lovers here got back to her post and read it if you missed it. She explains in a very easy to read way how and why "fancy" ferrets appear, deafness and other issues occur. It's really worth your time. Very enjoyable.
