Hello. I'm not sure if it's intentional, a bug, or just something devs didn't notice, but wildgoat hide, goat hide, and adder hide show the bottom (inside) part when hanged on the wall, while all others show the upper (outside) part. Viceversa, if you rotate the camera to see the room from the outside, you see their fur/scales instead of the cured inner part.
Here's some screenshots to show you what I mean:
