This is not a skull that I found or processed. I bought this from someone online, but I wanted to include it on the blog as part of my collection anyway.
I also want to include a photo of the damage that occurred after my cat played with it.
I believe this to be caused by the bleaching process the skull went through before it came to me. Excessive bleaching causes the bone to become incredibly brittle, and can cause yellowing over time. I do soak my bones in bleach for cleaning purposes, but not long enough to cause brittle-ness. Afterall, I quite like the 'natural' colouring of unbleached bones.
