Hi all, When my cat died, I buried her body and then two years later recovered the bones, hoping to articulate the skeleton. Needless to say, by this point there was no visible flesh or soft tissue left on the bones. They are, however, discolored. I heard of degreasing in acetone, so I have the bones currently soaking in a sealed glass container full of acetone. I'm wondering, if a skull was buried for that long do you expect it to still have a lot of grease? It's been soaking now for about a week and the acetone is still clear and colorless - am I supposed to be observing something to notice that it's working? When my cat was alive she was only ~7 pounds, so the bones are relatively small. How long should I wait, how do I know if the degreasing is working, what am I supposed to be observing, etc? Thanks so much!
