They could add the fur for a lot of different things:
--Make special dyes the color of the fur, by adding another ingredient - hopefully not impossible to get. Or
--Make a special food with it that when fed to your pet it will add +5 fire resistance up to max of 85 for one hour? Or
--Have Alchemy/tailoring mix with black rock fragments and cloth to make random very rare color cloth shirt or belt with random property on it (!). Or
--Have body sculptor transform it to random shape awesome hairstyle change for you, also with random color or the color of the fur. Or
--Added with leather, and other reg, make some pretty awesome colored shoes/sandals/boots? Or
--For cripes sake: Make it so that we get trash points out of the darn fur? Or
--Something other than just taking storage space?
