If you open the newly made black badger in a text editor, do you see a white color anywhere in the text? When I look at the original SVG the stroke color around the eyes is #f9f9f9. All other stroke colors are #000000, but there are a few areas that specify "stroke:none". Perhaps the latter cause the problem?
I did a search and replace on the black badger, and that fixed it.
